I tried install all the debug (dbg), dev and source packages I could find for each of the libraries that might be an issue. I attached the result of running thunar through gdb. FYI, the crash hangs mouse in the display manager, forcing me to kill the subprocess via ssh. The kill takes place between the line starting with 554 and execution of bt.
I did another few tests which might point to either X11 or the display manager. I can log in from another computer (this one running Mageia), remotely display thunar and moving an object does NOT crash thunar. Regardless, I attached the gdb output as requested. I tried installing the glib2 source to satisfy the missing gmessages.c but it didn't seem to find it. ** Attachment added: "thunar-gdb.out" https://bugs.launchpad.net/ubuntu/+source/thunar/+bug/1911036/+attachment/5466674/+files/thunar-gdb.out -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1911036 Title: GDK/GTK app crash when performing drag operation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1911036/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
