Bug 329384

Application: kdevelop (4.6.0)
KDE Platform Version: 4.11.3
Qt Version: 4.8.5
Operating System: Linux 3.11.6-4-desktop x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

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

I created a new include file and attempted to add a function declaration prior to saving for the first time; it crashed systematically upon typing the trailing semicolon. Saving the header file first successfully works around the issue.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
