The attached patch fixes an access violation when you want to show a 
modal widget but create a new child widget in the paint event. The issue 
is that the qt_try_modal() and tryModalHelper() functions do not test 
for "widget != null" and so tryModalHelper() crashes in that special case.

Andreas Hausladen
