location from cck filefield and i18n incorrect

I just discovered, that the location field in the generated xml file is set incorrectly when used in combination with the cck filefield for getting the file from and the i18n module which adds a leading language abbreviation to the url. Example:

<location>
http://www.example.com/en/files/videos/somevideo.flv
</location>

where it should say

http://www.example.com/files/videos/somevideo.flv

How to fix it? Here, also I attached a patch.

in xpsf_playlist.module change (line ~ 550)

$field = $node->{$fieldname}[0]['filepath'] ? url($node->{$fieldname}[0]['filepath'], NULL, NULL, TRUE) : $node->{$fieldname}[0]['value'];
to

$field = $node->{$fieldname}[0]['filepath'] ? xspf_playlist_url($node->{$fieldname}[0]['filepath'], NULL, NULL, TRUE) : $node->{$fieldname}[0]['value'];
