Duh, I got it, even without help from the list :-/

tal:define="client nocall:item/getClient" will return the *method* getClient and not the 
object returned by it, so it's obvious that a "python method" doesn't have such 
attributes as "absolute_url" or "id" :-)

The correct incantation is
tal:define="client python:item.getClient()"

BTW, the correct condition to test if the returned object is not None is
tal:condition="python: client"
and not
tal:condition="client" (which works but would cause the object to render).

Thank you again.
