Application: kdevelop (4.3.1)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-36-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

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

Kdevelop crashed while I was editing a c++ source file via the integrated editor. On restart I have been asked to restore the unsaved changes, which I have selected. Kdevelop crashed again. 

Now I can't restart Kdevelop, it crashes every time  I try to import my project by loading its CMakeList.txt.

I've already wiped out ~/.kdevduchain, myproject/myproject.kdev4 and myproject/.kdev4 with no success

My kdevelop version is the up-to-date version shipped with ubuntu 12.04

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
