[Evolution] problems with addressbook and users with multiple email adr

[Soeren Sonnenburg <evolution nn7 de>]

Hi!

Consider there is a user that sent 2 emails using different email
addresses.

One now wants to add this users email addresses to the addressbook.
To do so one clicks RMB on the users email and gets the first email addr
successfully added.
But now, when doing the same with the other email adr, evo complaints
that the user is already in the addressbook and refused to add this
email addr as the second email-adr.

Is this a Bug or Feature ?

thanks,
Soeren
