My Mozilla freezes today when opening the newsgroup The problem was the posting
<>. It contains a curious sign in the
subject.  Someone said this sign is "\uFFFC = OBJECT REPLACEMENT CHARACTER".

When this sign only is in the body (not in subject) Mozilla freezes when opening
the posting, not when entering the newsgroup.

Reproducible: Always
Steps to Reproduce:
1. Open Mozilla Mail/News
2. Subscribe to and fetch Portings at
least from 2004-07-29
3. Mozilla freezes.

1. Open Mozilla Mail/News
2. Subscribe to and fetch Portings at
least from 2004-07-29
3. Open <> (e.g. via MIDF)
4. Mozilla freezes. 

Actual Results:  
Mozilla freezes and must be killed ("kill mozilla-bin" with no special signal).

Expected Results:  
Show the posting instead and do not freeze.

I tried several older CVS Mozilla releases, from 2004-05-29 to 2004-07-28. Each
one has this problem.
Other people in the newsgroup do *not* have this problem.

Yes, with a completely missing ~/.mozilla.  Same effect.
the comments on bug 250718 might have clues

Maybe it helps when printing my about:buildconfig.  Here it is

Build platform

Build tools
Compiler 	Version 	Compiler flags
gcc 	gcc version 3.3.3 (SuSE Linux) 	-Wall -W -Wno-unused -Wpointer-arith
-Wcast-align -Wno-long-long -pthread -pipe
c++ 	gcc version 3.3.3 (SuSE Linux) 	-fno-rtti -fno-exceptions -Wall
-Wconversion -Wpointer-arith -Wcast-align -Woverloaded-virtual -Wsynth
-Wno-ctor-dtor-privacy -Wno-non-virtual-dtor -Wno-long-long -fshort-wchar
-pthread -pipe -I/usr/X11R6/include

Configure arguments
--prefix=/opt --disable-debug --enable-optimize --disable-tests
--disable-pedantic --without-system-nspr --without-system-zlib
--without-system-jpeg --without-system-png --without-system-mng --enable-mathml
--disable-xft --enable-freetype2 --enable-crypto --enable-strip
--enable-calendar --enable-xterm-updates --disable-ldap --disable-auto-deps

My Linux system is based on a SUSE-9.1, but with several self-built RPMs.

(BTW: The kill command when mozilla freezes of course is "killall mozilla-bin"
instead of "kill mozilla-bin")
