Comment 13 Sandro Mani 2015-06-16 11:05:43 UTC 
Yet another manifestation of qt5 screen handling issues. Upcoming Qt 5.5 (theoretically out by the end of the month) should contain lots of fixes, hoping things get better then.

Comment 14 Vladimir Shestakov 2015-06-16 11:29:00 UTC 
This crash happens only, if I've opened project, which used custom Kit and I've clicked the settings menu item.
When Desktop Kit is choosen, the settings dialog opens properly.
Comment 15 Sandro Mani 2015-06-16 11:46:51 UTC 
Is abosolutely no screen switching involved? (I.e. perhaps you started qt-creator with one screen configuration, and later on opened the settings dialog?)

If not (though it still looks like a qt5-qtbase bug), could you perhaps prepare a sample project (i.e. including the .pro.user file which stores the kit configuration etc) and attach it this bug? I'm unable to reproduce this issue without screen changes here.
