Application: kwin (4.8.5 (4.8.5))
KDE Platform Version: 4.8.5 (4.8.5) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-37-generic-pae i686
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Simply was booting up Kubuntu 12.04LTS for the first time, and popup declared that kwin had crashed, and asked that a report be filed.
- Unusual behavior I noticed:
This was different than other reports since it was after a fresh install, not from an update from another version of the same OS.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
