dump-emacs not compatible with toolbar-mode |

There is a bug that arises when using dump-emacs to preload your
Emacs. It seems that if the function find-image is called at any time
before the dump, starting the dumped image will result in an error and
startup will halt.
I just checked out a fresh copy of Emacs and built it a few hours ago,
to make sure the problem is not limited to my own snapshot.
Here is the command line I'm using to dump the image:
./src/emacs -q --batch --load bug_trap --execute "(dump-emacs
\"resmacs\" \"src/emacs\")"
Here are the contents of the bug_trap file:
------
(setq debug-on-error t)
(find-image '((:type xpm :file "toolbar/new.xpm" :ascent center)))
-------
Since certain packages call find-image directly or indirectly, there
are other ways to trigger the error. For instance, loading
php-mode.el or time.el before dumping will yield identical results.
Here is a backtrace of the error (this results from running "./resmacs -q"):
-------
Debugger entered--Lisp error: (error "Invalid image specification")
image-mask-p((image :type xpm :file "/home/bill/emacs/lisp/toolbar/new.xpm"))
tool-bar-local-item-from-menu(find-file "new" (keymap) nil)
apply(tool-bar-local-item-from-menu find-file "new" (keymap) nil nil)
tool-bar-add-item-from-menu(find-file "new")
tool-bar-setup()
tool-bar-mode(1)
command-line()
normal-top-level()
--------
Again, this error _only_ occurs if find-image gets called before the
dump. Also, the error does not occur in -nw mode; it only appears
when run in X.
I'd be happy to provide any clarification. Unfortunately, I'm not
familiar enough with Emacs' internals to provide a patch.
