Source file causing crash

Version:           unspecified (using KDE 4.6.0) 
OS:                Linux

When calling KApplication and for a particular combination of imports the
application crashes when closed (by clicking on close button of window, one can
also a Quit-button and close by clicking on it). Note that the particular
imports are relevant, removing for instance QVBoxLayout causes it to not crash.

Reproducible: Always

Steps to Reproduce:
1. Start the application.
2. Click on close window button.

Actual Results:  
Crash

Expected Results:  
Normal closure of application

Backtrace:

Application: Kontour (python2.6), signal: Segmentation fault
