Comment 1 for bug 874056

I dug a little , the issue doesn't appear with the revno 3866.
With some tests I "located" the problem in the new class xlgui.widgets.playlist.PlaylistModel Probably the interfacing to the this new class needs some change, I don't know, because I could not figure out where the event of tag changed is handled: I thought it was done in xlgui.panel.playlist, but it seems it's not.

I hope it helps.
