Problem with Nepomuk

I'm seem to be having another problem with 4.10.1 When I try to do a search for an email with Kontact I get an error message dialog box that reads. The Nepomuk semantic search service is not available. Searching is not possible without it. You can enable it in "System Settings". Nepomuk seems to be running and so is virtuoso-t. Any ideas??
