Application: kdevelop (4.7.0)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.17-4.towo-siduction-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

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

First of all - this *could* be a duplicate of issue #334950 - please check.

I just createda new python/Qt/Designer project. Took a new directory (was automatically created). When the wizard was finished, I clicked on  the "execute" button.
Kdevelop crashes then every time reproducible.

The crash can be reproduced every time.

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