Hmm. This appears to be the code that crashes: QFile file( Amarok::saveLocation() + "dynamic.xml" ); if( !file.open( QIODevice::ReadWrite ) ) { error() << "Can not open dynamic.xml"; return; } QTextStream stream( &file ); stream.setAutoDetectUnicode( true ); QString raw = stream.readAll(); This code itself seems OK to me. We're doing error checking for the file operation. So I assume something went wrong at a deeper level, e.g. Qt. Sorry, can't really do anything about it. We'll have to wait and see if it happens again.
I have just re-encountered this crash and filed it on bug 215773.
