Bug#56568: apt-get hangs trying to remove half installed package

[Chris Walker <chrisw@chiark.greenend.org.uk>]

Package: apt
Version: 0.3.10slink11

The dselect method of apt hung for >20 mins when trying to remove a
half installed version of emacs. I eventually gave up waiting.

dpkg --remove emacs didn't work either, but suggested I install emacs
and then remove it (which worked).

I got into this state by aborting an upgrade half way through when I
was worried my disk would fill up. This resulted in one of the emacs
packages being stopped half way through an install/upgrade.

Sorry to be a bit vague, but I did this last week and can't remember
all the nitty gritty details.
