Bug#352875: file-roller: Tries to guess format from file name

Hi,

The last part, foo.tar-1 seems to work fine now. This file is identified 
and opened by file-roller as a tar archive.

As for .tar-1.bz2 I'm not sure what can be done. Magic numbers can be hard to
do anything with as the file is identified as a bz2 compressed file either way.

$ file fb.*
fb.tar-1.bz2: bzip2 compressed data, block size = 600k
fb.tar.bz2:   bzip2 compressed data, block size = 600k

Can I mark this bug as done, or do you want to keep it open. (If it remains 
open, I will forward it upstream.)
