Add buddy + Authorize buddy duplicate buddies

[dmitriid]

This has happened to me with ICQ buddies

Somebody added me to their contact list and asked for my authorization.

Pidgin showed both a message box (see also ticket #3804 about this box) and a panel at the bottom of contact list both asking the same question - accept or deny?

I clicked "accept" in the message box and added the buddy to the appropriate group. The panel, however, didn't go away. As I clicked "accept" again, I again had to add this same user to the list and I ended up with two identical buddies (deleted one of them, of course).

Desired behaviour: when a buddy is added from one place, hide the other (if I accept from the message box, hide the pane and vice versa).
