 While trying do delete a Journal entry that has no data associated with it
 ("data" does not exist) and "should" contain a .xo, I get the following
 traceback:

 {{{

 }}}

 I've not been able to reproduce the bug that produced this entry, but
 Journal shouldn't crash on it anyway (there's no reason for datastore to
 consider the entry invalid, so any activity is free to produce something
 like this).
