I have also experienced this when surfing with firefox. I guess the relevant lines in my messages log are:
Aug 6 08:47:08 gandalf pulseaudio[18588]: pid.c: Stale PID file, overwriting.
Aug 6 08:47:12 gandalf pulseaudio[18588]: main.c: Unable to contact D-Bus: org.freedesktop.DBus.Error.NoServer: Failed to connect to socket /tmp/dbus-hPAdop8fkv: Connection refused
Aug 6 08:47:14 gandalf bonobo-activation-server (nilsfr-18699): could not associate with desktop session: Failed to connect to socket /tmp/dbus-hPAdop8fkv: Connection refused
I don't know if this is the consequence of Firefox killing the xsession (or dbus). I have attatched my syslog so you can see what happened around 08:47.
