#1462: cannot create an object without a file name

 If I create with the DataStore D-Bus service an entry with a file name of
 "" (as None cannot be passed through D-Bus), python complains that a
 string doesn't have a seek() method.

 Possible fix:
 {{{
 --- a/src/olpc/datastore/datastore.py
 +++ b/src/olpc/datastore/datastore.py
 @@ -115,7 +115,7 @@ class DataStore(dbus.service.Object):
              t = filelike.tell()
          content = self.querymanager.create(props, filelike)

 -        if filelike is not None:
 +        if filelike:
              filelike.seek(t)
              self.backingstore.create(content, filelike)
 }}}
