Seems to work for me with the last released rasqal 0.9.11:

$ roqet --version
0.9.11
$ roqet --source data.rdf query.rq
roqet: Querying from file query.rq
roqet: Query has a variable bindings result
result: 
[d=string("2006-04-14T16:33:01\n"^^<http://www.w3.org/2001/XMLSchema#dateTime>)]
roqet: Query returned 1 results

and the last released redland:

$ rdfproc --version
1.0.3
$ rdfproc test parse data.rdf
rdfproc: Parsing URI file:///Users/dajobe/data.rdf with default parser
$ rdfproc test query sparql - "`cat query.rq`"
rdfproc: Query returned bindings results:
result: [d=2006-04-14T16:33:01
^^<http://www.w3.org/2001/XMLSchema#dateTime>]
rdfproc: Query returned 1 results

where data.rdf and query.rq are the files you gave in your email.

Maybe you've got an older version of redland & rasqal?

( you can try the newer Subversion code at http://librdf.org/query too )
