Update:
I used KMimeTypeTrader::query() instead of KServiceTypeTrader::query() by 
accident.

Still, I found by the same accident that this method [1] with empty 
'genericServiceType' argument causes assertion[2]:

[1]
  KMimeTypeTrader::query(  	const QString & mimeType,
   const QString &  genericServiceType =QString::fromLatin1("Application"),
   const QString &  constraint = QString()	 ) 	


[2] Assertion (kservicetypeprofile.cpp):

KServiceOfferList KServiceTypeProfile::sortMimeTypeOffers( const 
KServiceOfferList& list, const QString& mimeType, const QString& gene
{
     initStatic();
     KServiceOfferList offers;
     KMimeTypeProfileEntry* profile = findMimeTypeProfile( mimeType, 
genericServiceType );

     KServiceType::Ptr genericServiceTypePtr( 0 );
     if ( !genericServiceType.isEmpty() ) {
         genericServiceTypePtr = KServiceType::serviceType( genericServiceType );
         Q_ASSERT( genericServiceTypePtr );
//^^^^^^^ here ^^^^^^^^^
     }


How about removing this assertion (or replacing with a warning), because 
otherwise default "Application" (#2) argument is a nonsense as if it causes 
assertion.
(or maybe the assertion cannot be reproducted outside of my system?)
