New description:

 Attempting to serialise a query containing a PostingSource subquery raises
 a UnimplementedError exception.  Much of the code to implement this will
 be part of the fix to ticket #295 - we will need to provide an extra
 argument to the Query::unserialise method() to provide a way to lookup
 possible PostingSource classes by name.

Comment:

 Changeset [11829] applies this patch, together with some tests, and fixes
 most of this bug.  It's not possible to serialise queries containing
 postingsources, so I'm updating the title and description to reflect this.
 Also marking this for 1.1.0, since it's just about done, and the final fix
 may require a tweak to the API.
