[gentoo-user] nepomuk/virtuoso using 100% cpu

[Alan McKinnon]

Since the upgrade to kde-4.6.3, nepomuk and/or virtuoso insists on giving my 
cpu a stress workout. usage is pegged at 100% and .xession-errors is full of 
junk like this:

"/usr/bin/nepomukservicestub(13816)" Soprano: "SQLExecDirect failed on query 
'sparql  select distinct ?r ?reqProp1 where { { ?r 
<http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#to> ?v2 . ?v2 
<http://www.semanticdesktop.org/ontologies/2007/03/22/nco#hasEmailAddress> ?v3 
. ?v3 <http://www.semanticdesktop.org/ontologies/2007/03/22/nc' (iODBC Error: 
[OpenLink][Virtuoso iODBC Driver][Virtuoso Server]SQ074: Line 1: SP030: SPARQL 
compiler, line 1: syntax error at '<' before 'http:' at '' immediately before 
end of statement)"

and this:

"/usr/bin/nepomukservicestub(13066)" Soprano: "SQLExecDirect failed on query 
'sparql  uboku' (iODBC Error: [OpenLink][Virtuoso iODBC Driver][Virtuoso 
Server]SQ074: Line 1: SP030: SPARQL compiler, line 1: syntax error at 
'uboku')"

kdepim is 4.4.11.1.
Everything else is at latest unstable.

I remember having to deal with this once before with an ill-fated experiment 
at using kdepm-4.5.95, but cannot for the life of me find what I did to fix 
it.

Anyone have some pointers?
