yes, that's exactly what's happening :) Matthias already fixed one krunner 
plugin that was doing this, but not he's faced with the 
Nepomuk::Query::QueryParser bits.

as it is internal to Nepomuk and it is using static members internal to the 
library (meaning krunner or any other app can't just use a "different Nepomuk 
object") QThreadStorage seems the easiest solution here.
