Ah, this clarifies it. TBC will actually prepend the namespace prefix declarations to your SPARQL queries so that you don't need to type them in manually. Apparently this algorithm should be more tolerant against the kind of namespaces that you have in your file. On the other hand, the bug seems to be somewhere else, because the namespaces end with a space character, which is invalid anyhow.
