Application: plasma-desktop (4.11.20)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-21-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

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

Trying to log into my session. Now happens about 3 times out of 4. Also, my computer freezes often, I do not know if that issue is actually related but when it does freeze, I am nearly certain I will get this bug afterwards.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Outil de gestion de fenêtres Plasma (plasma-desktop), signal: Segmentation fault
