OK, but note that this is a rather serious bug somewhere (perhaps
in aptitude, but really, I'm not sure since according to aptitude's
debug log, everything is fine on its side), not just a solver
limitation: if this were a solver limitation, aptitude would have
at least said that the upgrade was not possible because some
dependency could not be satisfied (this is what it usually does);
but this is not what happened.

In short, something attempts to remove a package that has *not*
been marked as to be removed. Fortunately, when trying to remove
the package, dpkg detects a dependency issue. But I fear, that in
some cases (e.g. when the unannounced package to be removed would
not have a dependency on it), this could potentially completely
break the system.
