SUMMARY
When adding some remote files to the playlist (e.g. a podcast episode without downloading it before), it appears as a local file after Amarok is restarted and is not accessible any more. The http protocol part and host name are missing from the URL, as is visible from the metadata dialog.

STEPS TO REPRODUCE
1. Drag any podcast episode which is not downloaded locally to the playlist
2. It can be played normally (i.e. streamed)
3. Restart Amarok


OBSERVED RESULT
The podcast episode appears in the playlist as a local file without the http protocol and host name part of its URL and is therefore unaccessible.

EXPECTED RESULT
The playlist item should be restored completely with the full URL so that it is also playable after restarting Amarok.
