Description Christian González 2014-11-30 00:39:33 UTC 
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

If you can reproduce it every time, please give us the following information:

launch the "kdebugdialog" application, and enable the following areas:
  - 9501 (kdevplatform shell)
  -  9503 (kdevplatform project)
then launch KDevelop from the console, and pipe all its output into a log file. reproduce the crash and attach the logfile to bug report 331227 please.

additionally, if you could also reproduce this crash inside valgrind, it would be also very interesting:

valgrind --smc-check=all-non-file --track-origin=yes kdevelop -s <your session> ...
