Christmas Pidgin Worms

I finished listening to "Letters from Father Christmas" by J.R.R. Tolkien a few days ago on audiobook cassette. At first I thought it was just a great series of letters, but when I read the liner notes and realized that his children actually received those letters every year growing up, I was thoroughly impressed!

We had some exciting virus/worm activity at work recently, a man-in-the-middle attack closely related to the "Trojan.exploit.131" exploit. Only lasted a few hours, though, before we got it all eradicated. Fun! (Not.) Speaking of work, we recently moved our warehouse at work across town, closer to the airport. Faster shipping for everyone!

Ok, here's a random question for anyone using Pidgin (the multi-network IM client): what do the different icons mean in this screenshot? I've looked at the Pidgin documentation, and see no reference to the icons at all:
