Only if there was an error that triggered that message.
What you want to do is type
/console taintLog 1
into your chat. This will log what happened and by what addon to a taintlog.txt file in your World of Warcraft\Logs folder. Then restart/reload the game and try to reproduce what got you that error. It usually occurs in combat, so you could go have a lvl 1 wolf beat on you or something.
