Bug 298585

Application: kmix (4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Started Firefox and Thunderbird at the same time directly after kde startup

- Unusual behavior I noticed:
The kate session manager has shown many empty kate windows on kde startup.
(Might be a unrelated bug)

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