Bug#565207: tasksel: no selections results in exim being replaced by citadel

[Sparr <sparr0@gmail.com>]

Package: tasksel
Version: 2.81
Severity: normal

I started with a fresh install from a squeeze netinst CD.  During the
install I deselected all tasks (the last one was selected by default,
I believe it was something like "common tools").
I upgraded to unstable via apt-get dist-upgrade.
I ran tasksel.  The list of tasks was slightly different than during
install, and Mail Server was already checked.  I unchecked it, leaving
nothing checked, and opted to Continue.  Over the next few dialogs
this resulted in most of exim4 being uninstalled and citadel
(citadel-server in particular) being installed and configured.  This
behavior seems odd, possibly buggy.
