This is because the field can now be NULL and there were places where this was not properly checked. So now a function call channel_get_name() should be used instead and is garaunteed to return non-NULL. In addition to this there is a nice added benefit. You can NOT set the name, and it will automatically pull the name from the first available service. This will not be persistent (part of config) unless you change that name and save from the UI. This means if the service name changes, so will the channel name. However on that last point there will not be, currently, any message sent to the clients (HTSP) to inform them of such a change. So there might be some lag in getting the update.
