Error when plugging iPod Touch into MacBook

Whenever I plug my iPod Touch (2nd gen) into my MacBook running Ubuntu 10.10 I get the following error:

DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)

It will show up in the file browser but whenever I try to mount it I get that error.

EDIT: I thought that this might be because I had it plugged into a dock, but I tried plugging it in directly to the MacBook with the USB Cable and it still does not work, same error message.

sudo add-apt-repository ppa:pmcenery/ppa
sudo apt-get update
sudo apt-get dist-upgrade

i did it yesterday, and worked flawlessly for me (4.2.1 iOS)
