 Steps to reproduce:

  1. delete .olpc.store from the usb stick if present,
  2. create a file on the usb stick with a '?' character on it,
  3. try to browse the usb stick in the journal.

 Problem:

  - the journal will show an empty screen

 Error:

 {{{
 ...,
 {'title': 'a\xe7a', ...},
 ...], 23) to message with signature aa{sv}u:
 <type 'exceptions.UnicodeError'>: String parameters to be sent over D-Bus
 must be valid UTF-8
 }}}

 Could be a problem with mounting usb sticks with the wrong encoding. See
 #3498.

 Perhaps we should at least make sure in the datastore that we are sending
 correct utf-8 strings through dbus?
