Bug#656552: zope2.12-sandbox: fails to upgrade from testing

[Andreas Beckmann]

Package: zope2.12-sandbox
Version: 2.12.23-1
Followup-For: Bug #656552

Hi,

the problem now also happens on a regular update from testing.

Adding set -x to the postinst script does not reveal any useful
information:

# dpkg --configure --pending
Setting up zope2.12-sandbox (2.12.23-1) ...
+ set -e
+ . /usr/share/debconf/confmodule
+ [ !  ]
+ PERL_DL_NONLAZY=1
+ export PERL_DL_NONLAZY
+ [  ]
+ exec /usr/share/debconf/frontend
/var/lib/dpkg/info/zope2.12-sandbox.postinst configure 2.12.22-1
debconf: unable to initialize frontend: Dialog
debconf: (No usable dialog-like program is installed, so the dialog
based frontend cannot be used. at
/usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 76.)
debconf: falling back to frontend: Readline
dpkg: error processing zope2.12-sandbox (--configure):
 subprocess installed post-installation script returned error exit status 10
Errors were encountered while processing:
 zope2.12-sandbox

Installing dialog does not help.
You should ask a debconf guru as that seems to be a debconf
related problem, /usr/share/debconf/frontend seems to be failing.
