Zombie clone windows created upon docking
Ubuntu Studio 14.04, GIT commit: 8c7a103 (self-built with Qt 5.3.0)
1) open musescore
2) open inspector
3) undock inspector
4) dock it again, same location
5) move main musescore window
Result: window moves, and inspector with it, but now I have an *additional* inspector window still floating in the position it was in when docked. i can then undock the "real" one, dock it again, and get *another* one of these zombies. As man times as I like - each docking operation creates another zombie clone. These clones stick around after exiting musescore, even open switching "workspaces" in ubuntu. Pesky little devils!
I assume this a Qt bug, and a serious one at that, but wonder if it affects anyone else? Probably Linux only, maybe Xfce (the desktop used by Ubuntu Studio) only?

no one zombies, behaves as expected.
I can no longer reproduce this, but I don't quite want to close it yet. It was persistent when it happened - I could reproduce it on command even after rebooting. I suspect that what changed is that I installed the Unity desktop. I'm not actually running it, but merely installing that package changed a bunch of stuff on my system.
I'd still be curious if someone running stock Ubuntu Studio using Xfce desktop with no other desktops installed can reproduce it.
