Application: kwin_x11 (5.10.2) Qt Version: 5.9.0 Frameworks Version: 5.35.0 Operating System: Linux 4.11.5-1-ARCH x86_64 Distribution: "Arch Linux" -- Information about the crash: - What I was doing when the application crashed: I ran "kwin_x11 --replace" from the KRunner (Alt+F2) - actually saved that into a script but I don't think that matters. This bug doesn't break anything except that a popup with "kwin crashed" appears. After the "restart" process is complete, everything works as expected. The crash can be reproduced sometimes. -- Backtrace: Application: KWin (kwin_x11), signal: Aborted Using host libthread_db library "/usr/lib/libthread_db.so.1".

As always backtraces from Arch are useless.
Just so I understand it correctly, you need information where it's "in ()", right? Sidenote: DrKonqi rated the backtrace with 3 stars so that should probably be changed then.
(In reply to Luca Weiss from comment #2) > Just so I understand it correctly, you need information where it's "in ()", > right? Yes and on Arch that's just not available. Arch is the only distribution out there which does not provide debug packages.
