Will amrok stopped I added a podcast to the playlist  when I started playing the podcast amarok crashed immediately. On restarting amarok it crashed again (before completing startup).
In order to get amarok to start I had to manually remove the podcast from current.xspf (in .kde/share/apps/amarok)

The lines I removed were
    <track>
      <location>http://downloads.bbc.co.uk/podcasts/radio3/musicmat/musicmat_20131116-1230a.mp3</location>
      <identifier>http://downloads.bbc.co.uk/podcasts/radio3/musicmat/musicmat_20131116-1230a.mp3</identifier>
      <title>MusicMat: 16 Oct 13: John Tavener</title>
      <creator>BBC Radio 3</creator>
      <album>Music Matters</album>
    </track>

My dynamic playlist contains
                    <follow>directlyFollow</follow>
(next track from the album which would be my suspect!)
The relevant thread traceback was

After successfully restarting amarok I then turned dynamic playlists off and played the podcast without a problem.

Reproducible: Always




Maybe I shouldn't have had dynamic playlists active with my settings when playing a podcast but the crash is undesireable.
