I am not sure where to place all this logic. Perhaps we need some kind
of high level client / error handler in aptdaemon or move those bits
into software-center, but this would make sharing with update-manager or
any other client harder.

The tough challenge is to integrate the problem notification dialog and
the resolution confirmation dialog into one single dialog.

I will think about it and talk to mvo.
