I have just found this issue. I'll be happier if you could ditch the merge and fix this still in the gsoc branch and let me review it here, because it may be a bit tricky.


src/core-impl/collections/nepomukcollection/meta/NepomukTrack.cpp
<http://git.reviewboard.kde.org/r/106042/#comment15093>

    You need to call notifyObservers() here, also ensure that all your methods are thread-safe. This depends on thread-safety of m_resource. If it is not, you'll need to add QReadWriteLock to NepomukTrack and use QRead/WriteLocker at places where you access m_resource.
    
    Also the plain notifyObservers() doesn't suffice, because NepomukTrack is hidden by MemoryMeta::Track. You'll need to make NepomukCollection a Meta::Observer, subscibe to all tracks you add to collection and implement NepomukCollection::metadataChanged( Track ) to call MapChanger( m_mc.data() ).trackChanged( track );
