For the benefit of others (the mailing list refused my email replies in much 
of this conversation): this problem is solved by doing the following as root 
on the container:

PROMPT> cp -r /root/.rpmdb/* /var/lib/rpm/
PROMPT> rpm --define '_dbapi 3' --rebuilddb

Debian puts the database away in a user-specific directory and uses a 
different db format ...

HTH.
