Unable to mount iPhone DBus error org.freedesktop.DBus.error.InvalidArgs: Mountpoint Already Registered

Binary package hint: gvfs

The above error appears upon plugging in my iPhone 3GS using a USB connection on Ubuntu 10.04. Attempting to transfer tracks to the iPhone results in this error:

"Error Transferring Track
Error while getting peer-to-peer dbus connection:
The name :1.140 was not provided by any .service files"

The interesting part is that I can unmount the iPhone get back into Nautilus and the iPhone icon will still be there on the left side pane. Unmounting from Nautilus does not get rid of the iPhone icon until I physically disconnect the USB cable from the iPhone. My other USB devices, such as the 2TB external iOmega hard drive, exhibit identical behavior. I'm guessing that this is a gvfs bug since it appears very similar to other gvfs bugs that I've found from a couple of years ago. I am using gvfs 1.6.2-1ubuntu1~ppa1. Please let me know if you need additional information.

I forgot to add that my iPhone used to sync work perfectly using this same Ubuntu PC as late as November 2010. There were no changes made to the iPhone, only updates to Ubuntu -- I'd like to emphasize updates; no new software was installed on this Ubuntu PC.

Confirmed using iPhone with iOS 4.3 on Natty. Error started after upgrading iOS from 4.1 to 4.3.
