software-center crashed with SIGSEGV in gtk_image_clear()

I ran the Deb Package 'ultrastar-deluxe_1.1.0-4_amd64.deb' but it had an unmet dependency so I closed the software center and after a short while this bug report came up.

The error did not happen a second time when I ran the package and then closed the software center.
