Bug#155621: apt: Internal Error: Couldn't configure a pre-depend - may be more descriptive

[Vladimir Michl <vladimir.michl@hlubocky.del.cz>]

Package: apt
Version: 0.5.4
Severity: normal

I'am upgrading from potato to woody. Because apt from woody tell me:
Internal Error, Could not perform immediate configuration

I upgrade manually libc, dpkg and apt (and dependencies) to woody versions.

Now when I run apt-get dist-upgrade apt tell me:
Internal Error: Couldn't configure a pre-depend

but what I can make to apt-get continue? Which package is problem?

After manual upgrade debconf to woody version, apt-get continue.
(I list Packages file from woody/main and search for Pre-Depend).

May be subject's error more descriptive? Which package(s) cannot configure?

Thanks
