compiz crashed with SIGSEGV in g_atomic_int_get()

[Jorge Castro]

Binary package hint: compiz

I deleted some .desktop files on my desktop. A few reboots later (for installing drivers, etc.) I noticed that the imported shortcuts in my desktop were now ? symbols, since I had removed the shortcuts.

I right clicked on one of them and unselected "Keep in Launcher", compiz crashed.
