Problems with ScriptingBridge and iTunes

Hello!

I want to retrieve the path to the currently played file in iTunes. I 
thought scripting bridge would be the perfect tool for this, however 
i've run into some problem. I have this code:

iTunesApplication *iTunes = [[SBApplication alloc] 
initWithBundleIdentifier:@"com.apple.iTunes"];
iTunesTrack *currentTrack = [iTunes currentTrack];
   
if ([currentTrack isKindOfClass:[iTunesFileTrack class]]) {
   …
}

The problem is, that the class of the object returned is _always_ 
iTunesTrack, and not iTunesFileTrack, as i expect it to be. If i run 
the following applescript code:

tell application "iTunes" to current track

I get a "file track", which makes it possible to fetch the path using 
the "location" attribute. If I, in the ObjC example, try [currentTrack 
location], I'm told that it doesn't respond to that selector.
I have made certain that the object is of class iTunesTrack by typing 
'po [currentTrack class]' in gdb.

Very thankful for help!
