[PyQt] pyqtdeploy app fails to show window modal dialogs

[lloyd konneker]

Nevermind.

The problem seems to be that I was parenting the dialogs to 
QCoreApplication.instance().activeWindow().  Instead, I now parent to an 
explicitly passed known window, and now the dialogs appear.

But it was working without pyqtdeploy.  So I suppose it was a race 
condition, that pyqtdeploy slightly changes the order(?) and timing of 
events?
