    Bug 749777 - Deleting current gradient from script leads to...
    
    GIMP_IS_TAGGED error and possible Gimp crash (core segfault)
    
    Fix again by restoring code I accidentially deleted in
    ae708d6419d6cd37c75547d86fcad35a09ce7a1f. I don't really understand
    what it is doing but better not remove it without understanding.
