[gutsy] second dpkg error in one day

[Samuel Thurston, III]

Hi there list,

As we are getting closer to the gutsy release i switched over a few
days ago.  As with each release I expect my twice-daily apt-get
dist-upgrade to break something on occasion.

However, twice today I've had packages break- and halt the
installation of other packages-  for a fairly common reason

The error in both cases (once with gimp2.4 and once with cupsys) is
that some non-essential file (readme in one case, and credits.txt in
the other) is trying to be managed by both the main package and the
lib* package at the same time.

My question is twofold:

first, is there a more user-friendly way of getting the rest of the
packatges marked for install to continue without issuing

dpkg -i --force-overwrite /var/cache/apt/archives/[package-name].deb

and second, is there anything the devs can do to avoid this?  why
would a lib file's credits or readme be overwritten by the main
package?

Thanks in advance for any answers/suggestions.
