I would say it is pretty reliable.  Deleting the ~/.pulse directory
fixed the problem on two systems  for me.  Make sure firefox is closed
when deleting the files and it will clear up the crash.

I have no idea why it works, nor do I particularly care.  I passed
along the workaround for anyone else who, like me, had a broken system
and wanted it fixed.  My setup quit working after a power failure so I
speculate that it may be related to file corruption in some file in
the .pulse directory.  It could also be related to having FF 3.0 and
3.5 installed simultaneously.
