User notices are displayed twice in the current buffer.
In the 'message redirection' options I selected 'default target' and 'current buffer' for user notices.

Also, if you receive a notice from the user you have a private conversation with (and whose buffer is focused), then the 'default target' seems to be a random channel you share with that user. Well, it's not entirely random: every time it takes a channel higher in the bufferlist (that is also shared with that user).
