Did this not show up on yours version or mine? It seems like it
should have shown up on mine since the second character is an ``i''.

It means that it is marked for purge (remove package and config
files), but it has not been purged yet. If you were to run
# dpkg -r --purge --pending
Then it would get removed. This is how tools like apt-get, dselect,
aptitude, and synaptic work. Setting selections then use --pending.
That is how they are all able to be stateful, even between different
apt front ends.
