Comment 12 Michael Catanzaro 2015-04-04 19:57:59 UTC 
Hm, that's a weird crash. The backtrace makes it seem that g_object_unref was established as an exit handler, but that can't be right. I guess a frame is missing. I will guess libsoup to be the most appropriate component for this bug, but most likely it will just get closed because the backtrace has no debuginfo.

Comment 14 Michael Catanzaro 2015-04-05 16:10:23 UTC 
Well, libsoup doesn't seem to establish any exit handlers. WebKit establishes a couple, but they look extremely innocent. Hm....
Comment 15 Diogo Campos 2015-04-05 16:15:34 UTC 
I have this crash on GNOME Abrt. If I could do a "debuginfo" thing it would help? If yes, what/how can I do?
Comment 16 Michael Catanzaro 2015-04-05 16:24:16 UTC 
It won't help in this case, thanks though.
Comment 17 Matteo Settenvini 2015-04-19 12:17:59 UTC 
Can I help with this? In abrt I have a pile of crashes identical to this longer than my arm.

If it happens pretty reliably, maybe attach with gdb before exiting, set a breakpoint on __run_exit_handlers(), and figure out what exit handler it is that's causing the problems? (Or alternatively, rebuild glib/libsoup/webkit/etc with -O0 to get a better backtrace.)
