I turned the phone off and plugged the USB in and got this..

Failed to mount "Nokia N900".
Rejected send message, 1 matched rules; type="method_call", sender=":1.161" (uid=1000 pid=3723 comm="exo-mount) interface="org.freedesktop.Hal.Device.Volume" member="Mount" error name="(unset)" requested_reply=0 destination="org.freedesktop.Hal" (uid=0 pid=1418 comm="/usr/sbin/hald)).

When I plug the device in I get this message... any idea?
