crash in NS, 23.1, while loading font

I reverted the  Jul 24 change locally:

"* nsfont.m (ns_findfonts): Correctly return fallback in match case."

and the bug outlined below went away, so I recommend revising or  
reverting this change before the release.

What bug was this change intended to fix?  Please reply ASAP.

Strange, the 07-24 change looks legit to me.  Can anyone on this list
reproduce the crash (by calling about-emacs)?  If so, please debug, or
provide a backtrace with debugging symbols.

I didn't file a bug because I don't have time to isolate this with the  
vanilla 23.1 source.  I wanted to report it asap though because the  
crash was rather reproducible in my branch and it was directly related  
to that change.

FWIW, I cannot reproduce it with an emacs compiled from git commit
f7519d6a353417fd043f3f0efb0fa75210cad134 dated Tue Jul 28 20:36:57
2009 +0000, doing this:

; ./configure --with-ns
; make bootstrap
; make install
; ./nextstep/Emacs.app/Contents/MacOS/Emacs -Q

and then typing C-h C-a. This should trigger the bug, right?
Well it doesn't happen for me.

I've checked in a fix to trunk and branch (entity instead of list must  
be returned in match () case).

Same here. I build on July 28 from git source. It does not happen to me
either.
