Florian Bruhin fff777404b Use QApplication.postEvent again 
We had some funny segfaults reported during scrolling (i.e. with
QApplication.sendEvent), and some code already had to use postpone=True
so there was no segfault...

So now we're back to postEvent again, and eliminated the main reason for
segfaults with it, which was re-using (and -posting) events which had
already been posted.

At least during tests this seems to run stable, let's hope it helps for
the people having crashes as well.
