nvidia video gnome-power-manager crashed with SIGSEGV in fclose()

Binary package hint: gnome-power-manager

I was trying to fix a problem with the display so I was changing some settings from the NVidia control panel. Not sure if it is related but when secondary display connected everything is fine. If only laptop display is running the display is stretched although the top bar is not affected and when the mouse go over the unity icon the names scroll out slowly and stay out.
