Segfault, possibly in xfce_tasklist
This is xfce4-panel 4.20.3 (Xfce 4.20) on Manjaro.
I can't really tell you anything about what I was doing when the segfault happened, because I wasn't doing anything particularly out of the ordinary, just browsing in Firefox. I think that's the same when this has happened before. It's fairly intermittent, which is obviously a massive pain to debug, especially since I haven't managed to get a debug log anywhere. I'll try to start xfce4-panel logging to a file and see if I can catch it.
The last time, I did get the attached coredump stacktrace (the symbols are from debuginfod, hopefully they're correct)
