TBL message: "no terms in field label"

[peter]

Firstly, thank you for the prompt and useful reply to my previous
post.

I am exposing my d2rq-generated ontologies with the built-in Ensemble.
All work bar one, and this one generates a message in the browser, but
this is clearly an exception handler for this trace in the log file.

Please can you advise? I thought was looking for rdfs:label, but this
all looks OK from inside TBC.

Peter

This looks like an honest to goodness bug to me, I'll send off-list
asking for enough information to reproduce. This is likely to be some
example data ... :(
