There is not enough information here to fix this bug. We need a short testcase
where the bug is?

1. download Firefox source
http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/1.5rc3/source/firefox-1.5rc3-source.tar.bz2
2. compile with my .mozconfig
3. run in gdb with firefox -g
4. browse http://www.ciao.co.uk/. It should crash.

There is not enough information here to reproduce really and the directions
were not followed at all.
