  When I reproduced the steps - got time out exception 
  **SPARQL-QUERY **
  
    SELECT DISTINCT ?item ?itemLabel WHERE {
      SERVICE wikibase:label { bd:serviceParam wikibase:language 
"[AUTO_LANGUAGE]". }
      {
        SELECT DISTINCT ?item WHERE {
          ?item (p:P31/ps:P31/(wdt:P279*)) _:anyValueP31.
          MINUS { ?item (p:P31/ps:P31/(wdt:P279*)) wd:Q5. }
        }
        LIMIT 10
      }
    }
