Comment 3 for bug 507360

Problem B) and C) only seems to happens when I try to put myself in two groups, and with ejabberd. I installed openfire, and there I was easily able to add myself to the roster.

As pointed out there, probably the solution is to add a function like tkabber has: show_own_resources.
