Cant' get tracks from an album and can't get album from tracks

[GoogleCodeExporter]

What steps will reproduce the problem?
1. call album.getTracks() and call track.getAlbum()

What is the expected output? What do you see instead?
Artist.getTopAlbums method returns a collection of albums of specified artist. 
when i invoke album.getTracks from that collection I got only null value

What version of the product are you using? On what operating system?
i'm using lastfm-java-0.1.2.jar running on Ubuntu 12.10

Please provide any additional information below.
I also tried the other way around by invoking Artist.getTopTracks. After 
getting a single track i invoke track.getAlbum() but this time i got a Null 
pointer exception

Artist.getTopAlbums does not return a track listing for each album. Similarly, 
artist.getTopTracks does not return the album information for each track. 
Hence, Album#getTracks() or Track#getAlbum() will return null when using those 
services, respectively.

A track listing for albums is only returned on album.getInfo calls. Please 
refer to the official documentation to see what data is returned by what 
services:

http://www.last.fm/api/show/artist.getTopTracks
http://www.last.fm/api/show/album.getInfo

Hi 

I tried Album.getInfo(band.getName(), album.getName(), key);
it worked for the first three times.

Now i got this error message:

[Fatal Error] :1:1: Premature end of file.

I think it's because of Caller.getInstance().setUserAgent(user)
when i removed it the same error appears

thanks in advance
