Bug 273438

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-4-desktop x86_64
Distribution: "openSUSE 12.1 Milestone 0 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: I put my laptop 3 times on suspend to ram. After the 3rd wake up, I unlock my session, work a bit (check mail with thunderbird) then let the laptop as is. After 30 minutes, it lock the screen with the sound. Then when I unlock the screen, I got that bactrace.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Outil de gestion de fenêtres Plasma (kdeinit4), signal: Segmentation fault
