	* app/widgets/gimpfiledialog.c (gimp_file_dialog_set_image): unset
	the filename if the image is unnamed.

	* configure.in
	* app/sanity.c: depend on gtk+ >= 2.4.1.

	* app/widgets/gimpthumbbox.[ch]: changed gimp_thumb_box_set_uris()
	to gimp_thumb_box_take_uris() since the function takes ownership
	of the list,

	* app/widgets/gimpfiledialog.c: changed accordingly. Removed code
	that worked around a problem in gtk+ < 2.4.1.
