Bug 275753

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

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

I was opening the cover of my notebook, which was in suspend-to-RAM mode. For a split second appeared the desktop without login screen. Then the display became black and after some seconds appeared the login screen (and then the KDE Crash Handler of course ;) ).

-- Backtrace:
Application: Plasma-Desktop-Umgebung (plasma-desktop), signal: Segmentation fault
