Exactly, *APT* should not do that... why is this reported against
dolfin?  I tried to reproduce this bug with aptitude instead of apt,
and it seems that aptitude is a bit smarter than apt as it doesn't
remove dolfin-dev but offers to upgrade it to the newer version.

IMO, this bug should be reassigned to APT. It also happens with
mingw-ocaml (see #662746). I'm CC'ing APT maintainers to have their
input on this kind of issues.

Followed steps to reproduce:
#0. cowbuilder-squeeze --login
#1. apt-get install --no-install-recommends dolfin-dev
#2. sed -i s/stable/wheezy/ /etc/apt/sources.list
#3. apt-get update
#4. note that `apt-get dis-upgrade` fails
#5. and that `aptitude full-upgrade` works
