Re: dump-emacs not compatible with toolbar-mode

[Bill Atkins]

I should also mention that this happens even if the particular image
to be loaded is not toolbar/new.xpm.  I use that in bug_trap simply
because that's what Emacs was choking on.  Once Emacs is running,
though, it can load new.xpm and any other valid XPM I've tried without
issue.
