printing with firefox3?

["Steven M. Bellovin" <smb%cs.columbia.edu@localhost>]

Is anyone else having trouble printing with firefox3?  I can't print
from two i386-current boxes; I can print from an amd64-current box.
(This is the first time I've ever had more luck with amd64 than
i386...)  All machines run cups.  One of the failing machines has

        PKG_OPTIONS.ghostscript+=cups
        PKG_OPTIONS.openoffice3+=cups
        PKG_OPTIONS.openoffice2+=cups
        PKG_OPTIONS.gtk2+=cups

the other has no such options set.  The problem is a segmentation
fault.  Here's a backtrace on the machine with the cups options:

I have reports of similar problems on 5.0beta.
