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?)
