Segafault when working with archives

Hello,

1. I'm experiencing random segfaults when working with archives. Whether it's a file-roller or xarchiver, it doesn't matter much. For example, when I select some folder or a bunch of files and choose to archive them, Thunar randomly closes. Or simply open Thunar, open some archive and start browsing inside of it. I've managed to start it from the console and reproduce it to see what happens (since it's a very random issue) and it just says 'Segmentation fault'. That's all.

Just thought that I'm not alone with this problem, maybe others would like to join this bug report.

Sorry if it's been reported already, but after searching here seems that I haven't found anything relevant.

2. Today I've experienced another interesting segfault. I have a folder with some .mp3 files and several .mp3.sfk files that were left after editing the songs in Sony Vegas under Windows. Anyway, I guess it can be just any other unknown (probably) to Thunar file types. So, when I open this folder, press Ctrl+A (to choose everything) and press Enter, Thunar segfaults.

I've managed to recreate it right now by putting an .mp3 file in a 'test' directory and created another, empty file (whatever the name, I named it 'test' also). Pressed Ctrl+A and Enter. Segfault.

Looks like I don't have debug symbols for Thunar in Arch and should recompile it with the appropriate option, but just don't have time at the moment. All I did was run 'strace Thunar' and got this:

--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x55a45bf4f44f} ---

But I guess it's not very informative.

I understand that it's a rare behavior for a user to choose all files in a dir (music ones + other, non-media files; or even placing non-media files with music, but, well... it can happen).

I'm using Arch and Deadbeef as an audio player. Xfce 4.18.4, Thunar 4.18.6. Always fresh and updated.

What's more bothering for me is the first issue I mentioned when I'm working with archives.

TIA

changed the description

1. […] Looks like I don't have debug symbols for Thunar in Arch and should recompile it with the appropriate option, but just don't have time at the moment.

Arch does provide debug symbols for many packages now, including Thunar. You can open the coredump in gdb and it will find debug symbols for you via debuginfod if configured to do so (I think it's the default), or you can install thunar-debug from the extra-debug repository. See

• https://wiki.archlinux.org/title/Core_dump#Examining_a_core_dump
• https://wiki.archlinux.org/title/Debugging/Getting_traces#Debuginfod

2. […] when I open this folder, press Ctrl+A (to choose everything) and press Enter, Thunar segfaults.

I can reproduce this one, here is the backtrace for Thunar git master 4.18.0+507+g6b0387bd:

Looks like Thunar tries to open both files (text and mp3) in VLC and Mousepad in my case, which is wrong, but I don't know if it's related to the crash.

added 1. Crash / Freeze label

Looks like Thunar tries to open both files (text and mp3) in VLC and Mousepad in my case, which is wrong

Yes, that's what happens, I guess.

And thank you for the Arch debug info. I'm pretty new to this distro. Do I have to debug it and provide here? Btw, have you ever experienced that 'archive issue' as well?

Do I have to debug it and provide here?

Yes please, just follow the steps in https://wiki.archlinux.org/title/Core_dump#Examining_a_core_dump it's really straightforward.

have you ever experienced that 'archive issue' as well?

No, not that I can remember.

mentioned in commit f7122514

mentioned in commit 859a264d

Thanks for reporting @AngryPhantom and for the trace @Tamaranch !

Yea, I could reproduce that multi-file-activate crash ... was a use-after-free. See commits above(master and 4.18 branch).

I as well cannot reproduce the open-archive crash. So yes, a backtrace would be very welcome !

I can confirm that the files are now open in their respective applications, and no more crash

changed title from Random segfaults to Segafault when working with archives

Guys, I'm sorry but I'm a bit at a loss. I'm using Artix actually (it's Arch based, but without systemd). Thought it would be easy but looks like it's not.

When I run gdb thunar I get this:

I'm pretty noob in all this. This distro also doesn't provide coredumpctl. Though they have a repo with -debug packages, but thunar-debug is 4.18.2 (not 4.18.6 like the current one). Should I simply install this additional package? What's next?

There's also a possibility to recompile thunar with --enable-debug option.

What's the step-by-step guide? What should be done first? Like, I'm running thunar and try to reproduce this bug and cause a segfault and then 'gdb thunar'? Right? Or what?

Sorry again for noob questions.

Hmm, not having systemd changes things quite a bit, you'd need to see Artix's own documentation in that case. As for the version mismatch between thunar and thunar-debug, maybe it's just a problem of mirror synchronization, or maybe the distribution is poorly maintained :)

In any case, for a non-reproducible crash, the easiest thing would be for you to know how to exploit the coredumps stored on your machine. Otherwise, you'll need to get Thunar to crash by running it in gdb (run command in the above terminal), and then get a backtrace from it (bt command).

maybe the distribution is poorly maintained

I agree this could be the case, but I already got used to it.

Well, since it's a really random and rare bug you may close the issue. If I decide to change distro some time in the nearest future and experience this bug again, I'll open a new one.

Thank you for your patience and time!

Alright, then let's close for now. As soon as you have a trace, please open a fresh issue !

Thank you for reporting!
