Crash when trying top open subfolders of an unreadable directory (via location bar)

Version information

Thunar 4.20.0 on Xubuntu

Steps to reproduce

Create a folder as root. (sudo mkdir testfolder)
Make folder unreadable. (sudo chmod 0700 testfolder)
In Thunar's location bar, type a path that is a subpath of that folder, the subpath doesn't have to exist. (example /home/user/testfolder/subfolder)
If "Open With" dialog pops up, pick Mousepad. (Not sure this matters, but that's what I did)
Continue trying to open subfolders via the location bar entry.

Current behavior

After a few tries, this creates a crash / segfault. The first time it didn't crash, but subsequent times (when it opened immediately without the Open With dialog), Thunar crashed. I tried this on Porteux linux with 4.20.0 to make sure it wasn't just my setup, and there it didn't crash immediately but after several tries it did.

I get this is a very edge case scenario but I didn't know if was related to #1538 (closed), or if it could cause problems elsewhere, so I figured I'd report it.

Expected outcome

No crash.

But also, probably blocking the attempted opening of these files/folders. If #1538 (closed) is related, and there is to be a dialog blocking the opening of unredable folders, it would make sense if Thunar also displayed that dialog and blocked opening of anything beyond that initial unreadable folder. Because this creates a situation where if you think you're opening a file via the location bar, and are unaware that it is in an unreadable folder, it might look like an empty text file was successfully opened (mousepad checks if it's readable, but many apps don't and will open a blank/new file). Also the folder is unreadable, so it's impossible to know if the file exists or not.

Backtrace

I'm not sure if I did this right. I did gdb then attach <pid of thunar> then did the steps above. After the crash did backtrace. If there is a better or more complete way to do this please let me know!

Additional information

Thunar 4.18.10 on Fedora 40 Xfce doesn't seem to do this.

Let me know if I can add anything more (or if the backtrace can be done better)! Thanks!
