unity-panel-service crashed with SIGSEGV in g_closure_invoke()

[ALexzander Marzouca]

Unity crashed when I was using chromium and Rhythmbox. Also, I have noticed (im not sure) some desktop corruption. The desktop (where the wallpaper is) has some glitches both in unity and unity 2d.

In the background (not update manager) you can see that it is glitchy. It's not like that at this moment but it gets like that.

Also in unity (not 2d) the words are corrupted such as the one in the up date manager
