Try to "amarok -l 'sftp://remotehost/my/file.mp3'" with some example file and amarok simply won't load it. It does not even replace the playlist with me.

Reproducible: Always

Steps to Reproduce:
Try to add a file which is not supported by the phonon-backend by default, e.g. http, to be sure that you are trying to use the KIO-Phonon fallback. kde-open copies the file and opens it in audacity for me, so there is nothing deeper failing.

Actual Results:  
No loading, no playback.

Expected Results:  
Loading into the playlist and playback.

This would really be handy not so much for sftp, but for smb:/ and especially for a pet project of mine, where you can stream load files from a torrent through KTorrent and open them transparently through kio with a "magnet://"-link reference (works similar to http:// links). Loading audio files from a torrent (especially once the slave properly supports directory listing) would allow to directly playback any file from the torrent, for example the ones from Jamendo.
