Application: kdevelop (4.2.2)
KDE Platform Version: 4.6.2 (4.6.2) "release 3"
Qt Version: 4.7.2
Operating System: Linux 2.6.34.8-0.2-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
This is reproducible with this small project example:
within kdevelop:
-create a new CMake-based project
-create a new subfolder 
-close kdevelop
without kdevelop:
-move the subfolder to some place outside the project file tree
-add a softlink to the new location of the subfolder as replacement 
-start kdevelop again and get a crash with the attached stack trace

The crash can be reproduced every time.

-- Backtrace:
