Heavy problems when rfemoving/installing packages

["Hans-J. Ullrich" <hans.ullrich@loop.de>]

Hi all,
since the latest days, something has changed on my sid/amd64-system
Whenever I want to install or remove a package, the installer crashes and stopping with this message:

This is just an example, the same messages I get at every package.

--------------------

LANG=C apt-get --reinstall install postfix

Postfix is now set up with the changes above. If you need to make changes, edit
/etc/postfix/main.cf (and others) as needed. To view Postfix configuration
values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

Any hints, what has happened, and how to fix this ?
