Banshee crashes with "Segmentation Fault" when using mp3 player in MTP mode

[Alex Moldovan]

Reproducible every time: open Banshee, attach mp3 player (Creative Zen Touch 20GB) and then it closed by sending a window with the following message:
Sorry, could not display all the contents of "Creative Zen Touch": DBus error org.freedesktop.DBus.Error.UnknownMethod: Method "Enumerate" with signature "ayssus" on interface "org.gtk.vfs.Mount" doesn't exist

From the command line using banshee --debug:

Device 0 (VID=041e and PID=4131) is a Creative ZEN Touch (MTP mode).

Tested with Creative Zen Touch and Sansa Clip. When switching the USB mode to MSC the Sansa player works fine. However, there's no MSC mode for the Creative Zen.
