[Qt-mobility-feedback] QMediaPlayer -> defaultServiceProvider::requestService(): no service found for - "com.nokia.qt.mediaplayer"

[Luoma Antti]

I have same env also in home and I had to copy / make links from plugin dlls to the /usr/local/Trolltech/Qt-4.6.0/plugins/mediaservice. Note that this was on Technology preview (not beta, running against 4.6.0). So it might be different in beta (in linux, didn't yet check that). If you wan't to check where QtMedia is searching those plugins at runtime set break points to QMediaPluginLoader::load() functions.
