[Interest] OS X 5.3 beta - QPrintDialog does not open

[Paul Miller]

Anyone else seen any print-related issues on OS X? There are no errors 
in the console, it just doesn't open.

I've deployed QPrintSupport.framework and 
plugins/printsupport/libcocoaprintersupport.dylib correctly, as far as I 
can tell.

I just tried Assistant and Print doesn't work there either. The same is 
true in Qt 5.2.1 as well. I wish I'd known how broken this stuff is 
before spending days porting from Qt 4.8 to 5.2.
