Got the same behaviour on my machine (Thinkpad T61). I explicitly reinstalled the whole system without using an old profile since I thought this was the cause. Unfortunately not.
Agree with the idea that it relates to Firefox. There are also no syslog entries when the crash occurs on my machine. Further, since I upgraded the nvidia drivers, the Capslock is no longer blinking on crash. There happens only a freeze without anything special. One thing I've seen was a segfault on starting Firefox once (started from commandline). Also there are permanently warnings about EMF stuff missing, don't know if this relates to here.
