Bug#612423: /usr/bin/debdelta: E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages

Version: 0.40exp
Severity: important
File: /usr/bin/debdelta
Hi!
Today while trying to run "debdelta-upgrade -v" I saw this:
debdelta-upgrade : E:Error, pkgProblemResolver::Resolve generated
breaks, this may be caused by held packages.
I have some packages on hold in aptitude (but not in dpkg) and it never
caused any kind of problem (actually debdelta also downloads the deltas
of the packages on hold in aptitude - #544582).
With a simple "aptitude full-upgrade":
=====
# aptitude full-upgrade
The following NEW packages will be installed:
libopenal1{a} python-bzrlib{a} xorg-sgml-doctools{a}
The following packages will be REMOVED:

The following actions will resolve these dependencies:
Remove the following packages:

yes, debdelta-upgrade simply calls
cache=apt.Cache()
cache.upgrade(True)
and that is similar to "aptitude full-upgrade" ; but it does not
implement conflict resolution

unfortunately this line ignores the list you give on command line... it
should not... but I would need some help from APT people, so that
debdelta-upgrade [files]
would more precisely mimic what aptitude does

if it ever happens again, there are two possible quick workarounds,
1) in /usr/bin/debdelta-upgrade, change temporarily the line
cache.upgrade(True)
to
cache.upgrade(False)
(if this solves the problem, I may add it as a command line option, or a
try:except fallback)
2) use the 'cupt' package manager, that solves dependencies (similarly
to aptitude) and then downloads deltas and uses 'debpatch' instead of
'debdelta-upgrade'
