Yes, the whitespace was missing from the continuation line. As for
distance-based bond determination, yes, that is exactly what I would
like to do. I am looking at the show_distances() method inside the
structure class. The usage of some of the optional parameters is a bit
unclear to me. Could you provide an example of how the show_distances()
method should be used?

OK. It would still be good for us to produce a clear error message.
Was it just the whitespace missing in the continuation line?

Would distance-based determination work for you? (As opposed to
user-defined bonds.) Look for structure.show_distances() in
cctbx/cctbx/xray/structure.py to get a start. Let me know if you need
more help. It is a fairly complex procedure because of comprehensive
handling of special positions.
The core data strucutre behind the distance calculations is the
pair_asu_table, which is closely tied to the asu_mappings class.
