gnome-thumbnail-font assert failure: *** Error in `gnome-thumbnail-font': munmap_chunk(): invalid pointer: 0xb6f3dc34 ***

Got that crash while opening .wine/.../windows/Fonts/ dir into nautilus

Looks like it is related to a fontconfig bug which possibly got a commit fix: https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/1195799
