 It appears to stem from this change:

         * isearch-mode.el (isearch-mode): Use overriding-local-map to set
         the keymap, not minor-mode-map-alist.
         (isearch-done): Restore overriding-local-map.
 
 
 What's happening is in Gnus summary mode I used to be able to
 isearch for a group and then hit M-g to fetch new mail in it.  In
 21.2 this instead runs the unbound (in Gnus) `goto-line' command. 
Does this patch fix the problem for you?

	* isearch-mode.el (isearch-mode): Set the current minor mode maps
	and the current local map as the parents to isearch-mode-map.
