Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic-pae i686
Distribution: Netrunner Dryland Second Edition

-- Information about the crash:
- What I was doing when the application crashed:
Just idle there.

I disabled screensaver and the screen would never be off when idling.  But Plasma desktop would receive SIGABRT after some time.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma 桌面 shell (plasma-desktop), signal: Aborted
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
