Created attachment 8349 journalctl crash report Thunar is crashing permanently and reproducible on one drive: https://forum.manjaro.org/t/thunar-crashes-how-to-sort-out-what-the-problem-is/79866
Same as for Bug #15212. Please provide a backtrace with debug symbols, and/or some more details on the use case .. what exactly you were doing in Thunar while it crashed ? Which view is used ? Which side-pane ?
I was searching for a file which contains a number at the beginning. - detailled view - tree - tool style (?)

Created attachment 9788 test diff With this change I get the crash when browsing a folder with image files.
(In reply to Theo Linkspfeifer from comment #4) > Created attachment 9788 > test diff > > With this change I get the crash when browsing a folder with image files. It seems like thumbnailer gets free'd before thunar_thumbnailer_queue_async_reply is run. However I don't think that's a valid reproducer and we can't just return if thumbnailer is NULL. It would be much better if you (or OP) could find a reliable way to reproduce the crash.
