Sometimes, when I am in an IRC channel, Empathy gets the IRC nicknames mixed up. Most of the time when this bug occurs, a person entering the channel appears to have the nickname "NickServ", when they really have a different nickname.

I cannot reliably reproduce this bug, but steps to reproduce are as such:

1. Enter IRC channel on Empathy
2. Enter IRC channel with separate nick under a reliable IRC client (such as irssi)
2. Wait for a user to join the channel
3. See if the nicknames displayed are the same under Empathy and the other IRC client

Here is an IRC transcript from Empathy (usernames edited to protect privacy):

  <yellow> we've had the fire on at our house for the last three hours
  <purple> yeah it's nuts
  <blue> I ran out of gas in my gas heater this morning
  <blue> not real good at all

However, the user that sent the last two lines was _not_ <blue>, it was actually <red>. My irssi client picked up the following:

  <yellow> we've had the fire on at our house for the last three hours
  <purple> yeah it's nuts
  <red> I ran out of gas in my gas heater this morning
  <red> not real good at all

At the time, the user <blue> was not even logged onto the server -- they had last been online several days ago. and my Empathy client had been restarted several times since then! Evidently, Empathy remembered the nickname somehow.
