Bug#652885: KDE 4.7.4 shows black screen if desktop effects are activated

[Antoni Mirabete i Terés <amirabete@gmail.com>]

Package: plasma-desktop
Version: 4.7.4-1

 When kde starts if desktop effects are activated shows only the first
 four icons of splash, when the last icon (kde icon) must be painted,
 screen goes to black with only the mouse cursor.

 When you press SHIFT+ALT+F12 to deactivate effects screen is showed correctly.

 KDE 4.7.2 don't have this problem, only a bit problem with render of
 shadows in combo-box that is also present in 4.7.4 when deactivate
 OpenGL 2 and some other options to activate effects without black
 screen problem.

 I use nouveau driver on 7 years old machine, with OpenGL 1.5 by Gallium.

 This problem can be a big problem for some users.
