Sentry Crash Report:

Description susundberg 2012-11-26 10:47:02 UTC 
Application: kdevelop (4.4.1)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-18-generic x86_64
Distribution: Ubuntu 12.10

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

I was editing the text as usual, project is not that large. I am suffereing maybe 4-16 crashes during 8h of work and this is starting to be quite painfull.

The crash seems to be non-repeated -- re-openening kdevelop and editing works fine, which makes this  hard to describe.

The crash can be reproduced some of the time.

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