	* plug-ins/common/jpeg.c (save_dialog): make the "Save EXIF data"
	toggle insensitive when no EXIF data is present (bug #140042).

	* app/display/gimpdisplayshell-close.c: as suggested by the HIG,
	ask the user to save the image when the last display is being
	closed. Addresses some issues raised in bug #106726.
