Bug 223281

Application: kscreenlocker (2.0)
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1))
Qt Version: 4.6.0
Operating System: Linux 2.6.32.4-desktop-0.rc1.1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

-- Information about the crash:
I put my display on laptop down, recover from sleep, work a few minutes, again suspend to RAM by closing laptop and quick recover, but there was no response, so I started to pressing some buttons (Esc, Enter, numbers, letters, mouse...) and get crash instead password window.

This is the first time it happens to me.

 -- Backtrace:
Application: KDE zámek obrazovky (kscreenlocker), signal: Segmentation fault
