I do remember that, at least at one point in the hardy buildup, I did
get an E-D-S upgrade to propose Evo removal (new E-D-S had already been
put available in the repositories, but not the corresponding Evo).
During Hardy development, the KDE4 updates would every so often cause
this.

Every so often I get this type of upgrade behaviour during new releases
build-time (and also on Debian -- duh --). So, you are not alone (and I
guess a lot of others have also seen/got hit by this). So yes, this is
interesting, but mostly to highlight the dangers of running Alpha code:
it can be very dangerous to run a blind dist-upgrade.

What I do to survive in the bleeding edge:

1. I never run 'apt-get dist-upgrade' and then say 'Y' to the changes
without checking what is being removed. Every time I am using a box that
is running the bleeding edge, I *never* run 'apt-get dist-upgrade'.
Instead...

2. I usually run Synaptic, click on "Mark all updates", then analyse
what Synaptic tells me -- and every so often I cancel *all* changes, and
go hunting for the, huh, bad, update(s), until I reach the one(s) that
propose to remove what I want to keep -- then I unmark the change(s),
and keep on. I guess once burned...

This process can be quite time-consuming if you dist-upgrade every few
weeks (a lot of changes to check on worst scenario)... but you will not
lose a loved piece of your system :-)

3. Still on Synaptic, after I have have /selected/reviewed all changes I
want, I go to "Apply", and -- again -- I check the proposed changes,
with special attention on the removal list (usually, if the "to be
removed" list header is not bold, then I just go ahead and commit).
Otherwise I again check what will be removed. I guess, sigh, twice
burned, etc, etc.

In fact, while I was typing this response, I went into Synaptic and ran
an update/mark all changes (so that I could get the actual headers), and
found one library being removed. I cancelled all changes, searched for
the culprits, and found that the update proposing the library removal
was doing so because it was also requesting a new package version of the
library to be installed.

So... this is, I guess, it. Please tell me if you consider my answer
satisfactory (or go ahead and close this bug, if this is the case).
