Test python script to reproduce setWindowTitle issue

plasmashell locks up when qt applications use setWindowTitle in quick succession. This was first noticed when scrubbing backwards and forwards through a multimedia file rapidly in the Tweak Software application RV.

STEPS TO REPRODUCE
1. Execute the attached python script (which requires the python-pyside package to be installed).

OBSERVED RESULT

The plasmashell taskbar locks up completely until the test application is closed.

EXPECTED RESULT

The plasmashell taskbar continues to respond.
