Here is a list of the value entries in tool-bar-find-image-cache:

((image :type xpm :file 
"/home/cyd/trunk/etc/images/gnus/toggle-subscription.xpm")
 (image :type xpm :file "/home/cyd/trunk/etc/images/describe.xpm")
 ("DEAD" . 19103923)
 ("DEAD" . 19103899)
 ("DEAD" . 19103875)
 ....

Looks like some of the lists in there have been garbage-collected.  This
is probably a GC bug.  Does the GC code know not to reap lists that are
stored in hash tables?
