Application hangs in the IEnumConnections->Skip method after calling IEnumConnections->Reset method

void hang1( IQTCrashPtr qtObject  )
{
	IConnectionPointPtr connectionPoint;
	IConnectionPointContainerPtr( qtObject )->FindConnectionPoint( __uuidof( IQTCrashEvents ), &connectionPoint );

	IEnumConnectionsPtr connections;
	connectionPoint->EnumConnections( &connections );
	connections->Reset();

	while( connections->Skip( 1 ) == S_OK) // will hang here forever (or for a _very_ long time)
	{
	}
}
