Bug 314452

Application: kdevelop (4.3.1)
KDE Platform Version: 4.8.5 (4.8.5) "release 2"
Qt Version: 4.8.1
Operating System: Linux 3.4.11-2.16-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

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

I added another target to set_target_properties(...) macro.

When it happened first time IDE restarted. 
I opened the same file pressed Ctrl+S and it crashed again. 
On the next start the IDE suggested to clean the cache, I OK-ed. And after Ctrl+S the same issue.

Meanwhile all changes to CMakeLists.txt were saved.

No modifications of CMakeLists.txt or other files were made outside the IDE.

The crash can be reproduced every time.

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