Bug 243917

Application: kscreenlocker (2.0)
KDE Platform Version: 4.4.90 (KDE 4.4.90 (KDE 4.5 RC1))
Qt Version: 4.7.0
Operating System: Linux 2.6.32-21-generic x86_64
Distribution: Ubuntu 10.04 LTS

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

I resumed from suspend and unlocked my screen, whereupon Kscreensaver crashed.

I don't know if the suspend and resume is relavant.

-- Backtrace:
Application: KDE Screen Locker (kscreenlocker), signal: Segmentation fault
