Bug 314048

Application: kded4 ($Id$)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-22-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
I woke up my computer (HP EliteBook 8560w) from Suspend to RAM, entered my password, and then I saw the Crash Reporting Assistant saying that the KDE Deamon has crashed. The screen brightness was low although the AC adapter was plugged in. I have not experienced any other problems or unusual behaviour.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
