As soon as I plug the device in any USB port, I get the following error message: "Unhandled error message: No such interface 'org.gtk.vfs.Mount' on object at path /org/gtk/vfs/mount/1" Yesterday, before the upgrade, I had to just plug the USB cable and the device was mounted automatically just like a pen-drive.
