I needed to run the who command, and was surprised to discover that my user was logged in three times. It was something like the following:
al@athene:~$ who al pts/1 2009-02-27 07:19 (:0.0) al pts/0 2009-02-27 07:19 (:0.0) al pts/3 2009-02-27 07:19 (:0.0)
Though the dates on one of the entries was different. Like an idiot I failed to copy the thing when it was showing.
I then shutdown and rebooted, and it now comes up with one login as expected. Why would this happen?
