 {{{
 DataStore.get_properties('a14032c6-d370-454f-9140-187178c36feb')

 when the object with id a14032c6-d370-454f-9140-187178c36feb is in a
 removable device, causes this exception:

 That object id was returned by DataStore.find() with the following
 arguments:

 {{{
 {'mountpoints': ['229af270-2461-4574-85d0-caa033ebba8e'],
  'order_by': ['-mtime'],
  'limit': 30}
 }}}

 This prevents resuming entries in usb sticks and copying those to main
 flash.
