Hmm, I am afraid I still need more details to understand fully what
you have in mind.  Can you give a step-by-step list of what might
happen and what would be bad about it?  For example:

  - User clicks on foo.install on downloads.maemo.org
  - Application Manager adds the maemo Extras repository with
    components "free non-free" and installs the foo package
  - User removes the "free" component from the maemo Extras catalogue

  -> Updates for foo will no longer be available

Note that in order for catalogues to be considered 'the same', they
right now have to have the same uri, dist, and component strings.

Maybe we should try to be smarter an merge catalogues with different
components but equal uris and dists somehow, but I don't want to get
too clever.  My idea is that the user either doesn't care about the
"Application Catalogues" dialog at all and is happy with what s/he
gets from .install files, or s/he knows what's going on and is not
