Disc number column emptied after play about plattenalbum

@Forage do forward this issue to MPD upstream as this affects multiple clients

Sorry, I'm not able to reproduce it here. It works perfectly fine. When you start mpdevil with -d is there anything printed on the console when the number vanishes except from the periodical status and some currentsong calls? Do the numbers reappear when you restart mpdevil?

The log gives me nothing out of the ordinary, unless it's the plchanges

A restart of mpdevil does not fix it, only switching between albums.

plchanges get run if and only if mpd reports a new playlist version. Something seems to make mpd change the playlist version all of a sudden.

A restart of mpdevil does not fix it, ...

This sounds like the bug is on mpd's side. Do other clients with a similar playlist view (e.g. Cantata) display the disc's correctly?
If possible please send me the output of this script (zipped archive) when the playlist is "corrupted". It will simply fetch the metadata of the whole playlist via python-mpd2 (the client library I'm using). This will help to determine if the disc tag gets transmitted correctly. If your server listens on a none standard port or is even on another host than the client you may have to change the credentials in line 4.

... only switching between albums.

What do you mean by that? Clearing the playlist and playing another album?

Using MALP to show the track details gives me a 0 for the disc number after a track has been played. It also appear to do a quick screen flash as if refreshing the whole playlist.

This disc metadata appears to not be provided by MPD any more afterwards.

By "switching between albums" I means clicking on a different albums while the first one missing disc numbers is playing and back again to the initial one. Effectively creating a new playlist.

I suppose we can call this issue closed as it's an MPD bug instead of mpdevil.
