Empty playlists when importing from copied itunes.

When trying to import itunes data, copied from my mac to my debian:
- when selecting import tracks, tracks are imported as expected
- when also selecting import playlists, playlists are empty, no music imported.

doing first the first and later the second, gives me my itunes music, but empty playlists.

this is on songbird 1.2 debian lenny.
i suspect this to be an absolute path issue, but if it can resolve the files, i would assume it would resolve the playlists too.

thanks
