backtrace

It is impossible to get backtrace from same tty, because if you run gdb, then at crash moment all desktop becames inresponsible (mouse can move, clock shows running seconds, keyboard not work, mouse clicks not work). So I run gdb from different tty. See attachment.

Comment 3 Frank Reininghaus 2015-11-22 18:04:33 UTC

Thanks for the bug report. Can you try to disable some of the the context menu plugins ("Services" in the Settings dialog) and check if that fixes the problem?

Comment 4 opensuse.lietuviu.kalba 2015-11-22 23:44:50 UTC

After more testing:
it most often crash, if mouse pointer fast pass Activities entry in context menu. Leaving context menu is not so danger. After dissabling activities service in Dolphin, I can no longer reproduce bug.

Comment 5 Frank Reininghaus 2015-11-23 21:10:41 UTC

Thanks for the quick reply. It's probably related to bug 351485 then.
