Bug 274500

Application: kdevelop (4.2.2)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

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

Just started Kdevelop and before any UI was visible, it crashed. emptied .kdevduchain folder before trying to start - same result.
KDevelop should have opened some bigger PHP Projects.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
