Issue with playlist.add in Lua Extension

playlist.add fails with "Playlist item should be a table" error. Posted details in forum here: http://forum.videolan.org/viewtopic.php?f=29&t=78750

And was told to submit this bug.

Example code:

mytable = {} mytable.path = { "file:///C:\myvideo.avi" } vlc.playlist.add(mytable.path)
