I have a playlist "Radio Playlist" that I have added several radio stations to.  Some of these have names, such as "WDIY", others only have a stream url (the name is the same as the stream url).

When I click to edit an entry so that I can put a nice name to the stream, I get the following error:

Slim::DataStores::DBI::Track->retrieve() parameters don't include defined values for all primary key columns (id) at P:/Music/SlimServer/trunk/server/Slim/DataStores/DBI/DBIStore.pm line 244

Note that in the past, I am sure I have edited the entries so all have nice names, but it seems that SlimServer hasn't written the name data to the playlist file on disk, so upon a full rescan the names were lost.  I have looked at the playlist file on disk "Radio Stations.m3u", and it currently contains the following:

i.e. the file doesn't contain #EXTM3U and #EXTINF instructions.
