Comment 5 Markus Krötzsch 2012-02-11 16:20:44 UTC 
This is very strange. The queries are not malformed SPARQL, and if I run them on my 4Store v1.1.3 directly, then they do not cause any problems. I also don't get results (since I don't have your data) but I can change the namespaces and URIs so that I get results also on my machine.

However, your report helped me to find another small problem: the error message reported that the update endpoint had been used, although the query endpoint has really been used (also in your case, according to stack trace). This is fixed in r111244. But the other problem I can only close as "works for me".

If the problem still occurs, you should try to run the offending queries on your machine (via http://localhost:8000/test/) and see what the exact error message is (if any). If it turns out that the query is really broken, we can fix it in SMW (and you can reopen this bug). If the query is accepted or if it leads to an error in spite of being correct SPARQL, then the problem is with 4Store and should be reported there.
