Applescript bug in new iTunes 7?

Question

I have used the following applescript (in an Automator workflow) with version 6.x of iTunes in the past:
-- Delete tracks from library and return the file location(s)
on run {input, parameters}
set these_tracks to the input
tell application "iTunes"
set these_files to {}
-- get the file path of each of the selected tracks
repeat with i from 1 to the count of these_tracks
set this_track to item i of these_tracks
if the location of this_track is not missing value then
set the end of these_files to (the location of this_track)
end if
delete this_track
end repeat
end tell
return these_files
end run
This script would take iTunes items and extract their file paths, remove the track from itunes and then pass the file paths to the next action.
Once I upgraded to version 7 it now fails on the "delete this_track" line:
iTunes got an error: file track id 4771 of user playlist id 4745 of source id 39 doesn't understand the delete message. (-1708)
Is there any way to verify this is a bug and send in a bug report for iTunes?
Thanks,

I was using the speakers before the update and they were fine. I use them for other things and they are fine, so it isn't the speakers, its the upgrade.
