freebsd stable - Jan 2007 - Firefox won't start on SPARC64

Hello all!

I'm having a few problems with Firefox here on this box. As you can see,
Thunderbird seems to work fine. But Firfox just exits with segmentation
fault (Exit 139) - before anything is ever displayed.

Is this a known problem or do I have to go looking by myself?

I am currently running this:

  FreeBSD sunny.rz1.convenimus.net 6.2-PRERELEASE FreeBSD
  6.2-PRERELEASE #0: Sat Jan 13 17:39:47 CET 2007
  root@sunny.rz1.convenimus.net:/usr/obj/usr/src/sys/SUNNY  sparc64

Has anyone else had this problem?

Regards
Chris

Ok, that was dumb. I was actually planning to write this with
Thunderbird, so you can't really see it. But let me assure you,
Thunderbird works fine. :-)

What I forgot to write was that I tried to install Firefox with 
pkg_add -r. This is only a Sun U60 and compiling big things like Firefox
isn't much fun as it takes forever. After Firefox refused to start I
removed it again and built it myself with the port. The effekt was the
same though - segmentation fault.

Can someone help me with this?

Chris
