Bug 314522

Application: kdevelop (4.5.60)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-36-generic-pae i686
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed: every time I open kdevelop, it crashes, wiping out kdevduchain doesn't work.

as of now, kdevelop is unsuable to me.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
