Hello Nunos,

Have you tried using a `ptr` that comes from another application? I think that's 
the context in which I get the crash.

I'll keep your code in mind though; the crash issue also reminded me that KF5 
KWindowSystem doesn't yet have a plugin (backed) implemented for OS X, so I'm 
porting the one from KDE4... Fun times!
