Bug 281714

Application: kdevelop (4.2.2)
KDE Platform Version: 4.6.5 (4.6.5) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-1-686-pae i686
Distribution: Debian GNU/Linux testing (wheezy)

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

After making several changes to my project (adding functions, changing private and public methods), I scrolled down a long cpp file and while that suddenly kdevelop crashed.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
[Current thread is 1 (Thread 0xb2cc0720 (LWP 14789))]
