Songbird doesn't auto-update

If you installed songbird with a .deb package, there's a little bug with it. It won't update properly due to the permissions in songbird's folder.
To fix it simply type

$ sudo chown username /usr/share/Songbird -R

replacing username with your user.

Then restart songbird and go to help->Check for updates and enjoy the new 0.6 version!

Cheers.
