Thanks, those stack traces are exactly what we needed. I can't find any other reports of those crashes, but that's likely just because nobody else had debugged it with GDK_SYNCHRONIZE yet... Next please report the bug to the developers at https://gitlab.gnome.org/GNOME/gtk/-/issues and remember

I tried that as I mentioned above. It doesn't crash in that scenario. I can ssh in from another computer and run thunar but I can't reproduce the crash this way. This is why I think it might have to do with the X11 server or lightdm. I can see if I can mess with xauth to run via ssh and keep it

Hi Daniel, I never removed GDK_SYNCHRONIZE from /etc/environment. It's been set that way for a few reboots. In addition, I confirmed it was set to 1 before running gdb. I'm wondering if you're not getting as much as you'd expect from the backtrace because I had to kill the thunar process.

Thanks for those crash reports. Unfortunately they don't have any stack traces for some reason... Since you seem to be pretty technical, the next steps I suggest are: 1. Install the debug symbols for gtk and apps like thunar. 2. Attach 'gdb' to thunar or any affected app. 3. Reproduce the
