Application: kwin (4.11.8)
KDE Platform Version: 4.12.4

Operating System: Linux 3.13.10-200.fc20.x86_64 x86_64
Distribution: "Fedora release 20 (Heisenbug)"

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

Just booting up. I reboot fairly seldom, so there were most likely a rather large number of updates to the system inbetween reboots, if that may be of any relevance.

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