Created attachment 652743 [details] [diff] [review]
Check that aViewToPaint->GetWidget() is not the nullptr

What about the attached patch?
At least it fixes the issue for me.

I meant bug 770424.
tn: Do you have any ideas here?

It appears that the view we got in PaintWindow via nsView::GetViewFor is returning null for nsIView::GetWidget(). Does that make sense?
The problematic view looks to be a view for a plugin. It looks like plugin views have always had their widget field unset (ie null), so I think the problem is that we are getting an expose event at all here, where we didn't get one at all before.
