[OpenWalnut-Dev] [BUG] Empty/white dialog boxes when using WUIGridWidget

[Christof Pieloth]

Hello OW Team,

I found a problem with modules which are using WUIGridWidget. If you add 
a module with an opened WUIGridWidget all dialog boxes, e.g. save 
project or file picker, are empty/white, see attached image.
If you have the module added, but no view was opended so far or the view 
is closed on start, the dialogs are ok, e.g. you can choose your file. 
The error does not occur in our modules which are using a WUIViewWidget.
I can reproduce the bug with the Template UI module on our 64bit Ubuntu 
12.04 and 14.04 machines. 12.04 is using Qt 5.3.2 from the online 
installer and 14.04 is using Qt 5.2.1 from the repository.

hg bisect tells me that the error appears first in:
