[emms-help] Problem with emms-start in Playlist buffer after emms-browse

[John Sullivan]

To reproduce:

1. See config below
2. emms-browse-by-album
3. RET on an album
4. emms-start

The cache was restored from a previous session. It was initially generated with
emms-cache-set-from-mpd-all. There is no nil track in the .emms-cache file.

Backtrace:

Debugger entered--Lisp error: (error "Don't know how to play track: nil")
  signal(error ("Don't know how to play track: nil"))
  error("Don't know how to play track: %S" nil)
  (if (not player) (error "Don't know how to play track: %S" track) (let (...) 
(funcall ... track)))
  (let ((player ...)) (if (not player) (error "Don't know how to play track: 
%S" track) (let ... ...)))
  (if emms-player-playing-p (error "A player is already playing") (let (...) 
(if ... ... ...)))
  emms-player-start(nil)
  (if emms-player-playing-p nil (emms-player-start 
(emms-playlist-current-selected-track)))
  (unless emms-player-playing-p (emms-player-start 
(emms-playlist-current-selected-track)))
  emms-start()
  call-interactively(emms-start)


Here's the (very messy) config I'm using:
