It seems that on your setup there is no icon associated with the mime
type for the ".spec" and there is no fallback by the gnome/gtk
functions (weird) and we don't handle that nicely. I can't reproduce
here (.spec mime type is text/x-rpm-spec and icon is the text file
one). I suggest you file a bug so we can fix this. It's probably just
a missing null check somewhere.
