In NamespaceManager.compute_qname it is possible for the variable name to be unbound when a namespace is used as a predicate e.g. ns2: and the namespace itself cannot be split any further. Fixing this usually just kicks the can down the road because the only reason to hit this condition is that you are trying to serialize a predicate that has no valid NCName form into an xml format that requires one, making it impossible to complete the conversion. That said, this fix should make it easier to understand what is going on by unmasking the real issue.

The new test graph will produce the UnboundLocalError with the old code that is missing the name = '' assignment. The new code correctly produces the xfail ValueError when trying to convert to xml.

I will merge tomorrow if there is no further feedback. |
