Title:
  gnome-session crashed with SIGSEGV in g_object_unref()

Status in “gnome-session” package in Ubuntu:
  New

Bug description:
  I'm using 2 monitors 2560x1440. At some time primary monitor lost image with 
"no signal", second just freezes, in 10 seconds image restores on both 
monitors, but FPS is so small (just several FPS), that I can't work until 
reboot.
  This occurs third time, so, this is not some random situation.
