mpd.playlists[index].songs breaks when playlist contains non-existent file

[kyv]

If a playlist has an internet radio or an erroneous file the .songs method throws the exception:

TypeError: no implicit conversion of Symbol into String

I would expect the the method to return a list of song objects as stated in the playlist. Perhaps some checks could be made for interet radio. Or perhaps return nil for those songs which do not exist. Or worst case provide an error indicating which playlist and file produce the error. In my case, the playlist has two good files and just one bad, and it took me a while to track down the problem.

To confirm just echo some erronous fileames or an internet radio url into an .m3u file in mpd's playlist directory and parse it with ruby-mpd. Heres the trace:

I'll look into it this weekend, don't have much time today. Or you can look into it, if you wish?

I will investigate further, but any help is appreciated.
