Application: kdevelop (4.0.2 (using KDevPlatform 1.0.2))
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-31-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
Here the steps:
I started kdevelop, it found the only project "libX11-1.3.3" (whose sources come from Ubuntu 8.10 libX11 sources), the analyzer started its parsing, then it crashed.

The crash can be reproduced every time.

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