Application: kwin (4.11.1)
KDE Platform Version: 4.11.1
Qt Version: 4.8.5
Operating System: Linux 3.11.2-201.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
Rebooting the system. 
During boot I noticed a screen opening while the KDE Login Splash was still running. 

Things I changed: 
A new script in the ~/.kde/env folder and the ~/.kde/shutdown folder. 
Those get executed with the desireable results. 
Probably not related

-- Backtrace:
Application: KWin (kwin), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
