	* plug-ins/common/file-gif-load.c
	* plug-ins/common/file-gif-save.c: for the most common errors,
	pass the error message with the return values instead of calling
	gimp_message().

	* plug-ins/common/file-png.c: unmarked a string for translation.
	This error condition can't possibly happen.

	* plug-ins/common/file-svg.c: also return an error message when
	the thumbnail can't be loaded.
