By the way, I also can't reproduce this. Sometimes it will happen, sometimes it won't. I thought it was related to a kwin effect such as switching virtual desktops or the overview effect but I can't find any correlation. All I know is that it will occasionally crash, forcing me to have all my work saved at all times. If it crashes, I lose all my progress after that. Then KWin and Plasmashell restart.

Can you provide a backtrace with debug symbols please? Without that, this bug report is inactionable.
(In reply to Vlad Zahorodnii from comment #1) > Can you provide a backtrace with debug symbols please? Without that, this > bug report is inactionable. This bug report is relatively old and I haven't had crashes of this kind for a long time now. But also, since I couldn't attach gdb to it previously and being a crash of the entire compositor also didn't allow drkonqi to launch, I don't think I could have provided a much useful backtrace with debug symbols in that circumstance. Maybe I'm missing something but since it's so old and I didn't experience it again, I'll mark this as resolved and if it happens again, I'll submit a new one and try to attach a more useful backtrace.
