Do not require GTK to be either present or usable to start. Before, we only checked that we could import GTK, but in a linux console, it's possible to import it while not being able to start it (no X11 present). This should resolve https://bugzilla.redhat.com/show_bug.cgi?id=646079 Thanks to Tom Spura for reporting it.
