Insane focus behavior...
TEST CASE:
1. Open a nautilus window
2. Minimize it
3. Open a gedit window
4. Minimize it
5. Press Alt+Tab and choose Desktop
Desktop is now focused
6. Press Alt+Tab and choose Desktop again
gedit is now focused, but is not shown (!)
7. Press Alt+F4
gedit is closed
nautilus is restored and gets focus (!)
8. Press Alt+Tab again and choose Desktop
9. Press Alt+Tab again and chosse Desktop (yes, again...)
10. nautilus is focused
11. Minimize nautilus
the window looses focus, but is still shown (!)
12. Try to close nautilus window
you can't, the window decoration is dead (!)
