gnome-software crashed with SIGSEGV in g_type_check_instance_is_fundamentally_a()

[Wise Melon]

This happened very soon I did a 'dist-upgrade' using apt-get and upgraded the package mtools. Other than that I hadn't done anything, I didn't even launch gnome-software myself so I don't know why the error came about as I wasn't doing anything special which I don't normally do after turning on my machine.
