KMainWindow unit test crash, caused by recent Oxygen commit

[Hugo Pereira Da Costa]

I could reproduce the issue with both kxmlgui_unittest and 
kmainwindow_unittest
Oxygen was the curlpit indeed. (there was a real flaw in the code, 
thanks to Thomas for pointing it out).

Should be fixed with
http://commits.kde.org/kde-workspace/68dbf302f2cb7bb011bdbd52e8dda04902a1dae5

Sorry for the trouble,

Hugo
