We've stumbled upon a problem with the query printer in SMW 1.6.1 and
1.6.2. Any export to RDF (example: [0]) triggers the following exception:

"""
Catchable fatal error: Argument 1 passed to
SMWExporter::addPropertyValues() must be an instance of SMWDIProperty,
instance of SMWPropertyValue given, called in
/var/local/mediawiki/extensions/SemanticMediaWiki/includes/queryprinters/SMW_QP_RDF.php
on line 72 and defined in
/var/local/mediawiki/extensions/SemanticMediaWiki/includes/export/SMW_Exporter.php
on line 150
"""

var_dumping $printreq->getMode() in
SMWRDFResultPrinter->getResultText() reveals the values int(2) and
int(1), i.e. PRINT_PROP in which case $printreq->getData() returns an
SMWPropertyValue object and not the required SMWDIProperty.

Setting the format to "debug" returns "Fatal error: Call to a member function getCount() on a non-object in /var/local/mediawiki/extensions/SemanticMediaWiki/specials/AskSpecial/SMW_SpecialAsk.php on line 426"

Let me know if you need more data.
