I experienced a very similar error, but not exactly the same, when trying to format a 4G USB 2.0 device. Matt's suggested workaround (near the very top of this report, using dd) worked after a couple of tries. I was getting "DBus.Python.GLib.Error" when trying to format, with the same consequences as described in this report.
