Application: kdevelop (4.0.0 (using KDevPlatform 1.0.0))
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Kdevelop crashes if I try to build (using F8) while editing the project's makefile.

Here's how to reproduce it.
1. Open some custom makefile project.
2. Edit something in the Makefile
3. Press F8 (NB:  buildset contains the 'all' target)

Result: Kdevelop crashes with SIGSEGV

Expected result:
Kdevelop sould not crash.


The crash can be reproduced every time.

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