Description Matouš 2016-04-01 11:27:33 UTC

Application: kwin_x11 (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.15-8-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

I just started the system normally...

- Unusual behavior I noticed:

After the openSUSE loading logo the applications didn't start as expected. I was asked for KWallet password and after closing this dialog there were no more windows, only black screen with cursor.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Unfortunately the debug symbols for kwin4_effect_builtins are missing. Could you please install the debug symbols for it and attach a new backtrace. Without it we cannot know which effect triggered the crash.
