Firefox BUG

[Hisashi Naito]

output of umane -a

FreeBSD bsdserver01.math.nagoya-u.ac.jp 7.4-PRERELEASE FreeBSD 7.4-PRERELEASE #26: Thu Feb 24 21:28:09 JST 2011     root at bsdserver01.math.nagoya-u.ac.jp:/usr/obj/usr/src/sys/20090203  amd64

version: firefox-3.6.13,1

When running firefox, and click header menu bar (example "File" and
etc...),  then firefox is crashed and output "Bad system call".

This bug is always reproduced.
