Hi Jonas,
To the release team: I think a fix can wait for a point release.

"apt-get install evince-gtk" does not result in a working postscript
viewer. Workaround: install the ghostscript package, which has a
versioned dependency[1] to avoid mismatches with libgs.
libgs relies on the main ghostscript package for support files in the
"/usr/share/ghostscript/8.71" directory. I ran into this because it
means that installing ghostscript 9 from experimental breaks
postscript support in evince and okular.
A proper fix would presumably be to move the /usr/share/ghostscript
files to libgs8 or a new libgs8-common package. The relevant
dependencies would be
ghostscript --- Depends: ${shlibs:Depends}
libgs8 --- Depends: libgs8-common (= ${source:Version})
Very simple.
Here's a more ugly and targetted fix. Thoughts?

Subject: libgs8: Depends: ghostscript
libgs8 has an undeclared dependency on support files from
/usr/share/ghostscript/8.71 in the ghostscript package.
More precisely, current libgs8 requires ghostscript 8.71. Rather than
hard-coding that (making it easy to forget to update the dependencies
in a later update), this patch relies on the current versioned
dependency Depends: libgs8 (= ${binary:Version}) that was added to
ghostscript a couple of years ago to address the same problem
(Bug#470253).
Yes, after this patch ghostscript would once again have a circular
dependency.

Untested (testing with apt and aptitude of the upgrade path from
lenny would be especially welcome).
