My .xsession-errors is spammed with messages from nepomuk and soprano. At this
point the virtuoso-t binary takes as much CPU as it can for hours. The messages
are similar to the following and seem to be the result of a bad query
construct:

[/usr/bin/nepomukservicestub] "/usr/bin/nepomukservicestub(2025)" Soprano:
"SQLExecDirect failed on query 'sparql  select distinct ?r ?reqProp1 where { {
{ ?r <http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#isRead>
'false'^^<sopranofakes:/booleanHackUntilVirtuosoProblemIsResolved> . } UNION {
?r <http://www.semanticdesktop.org/ontologies/2007/08/15/nao#hasTag>
<nepomuk:/re' (iODBC Error: [OpenLink][Virtuoso iODBC Driver][Virtuoso
Server]SQ074: Line 1: SP030: SPARQL compiler, line 1: syntax error at '<'
before 'nepomuk:' at '' immediately before end of statement)"


Reproducible: Always

Steps to Reproduce:
Just turn nepomuk on.



I am using the kdepim 2.0.89. The faulty queries might come from the akonadi
feeders.
