Stall on postinst of zope-zwiki_0.9.9-2_all.deb, please help

[Ken Causey <ken@ineffable.com>]

I'm having a problem installing zope-zwiki_0.9.9-2_all.deb from
testing.  Once it get's done with the postinst step it stalls.  I'm not
sure how to go about debugging this.  I changed the first line of
/var/lib/dpkg/info/zope-zwiki.postinst to

#! /bin/sh -x

to see if I could figure out what is going on, but it looks like it
exits fine.  You will note in the logs below that I have a slightly
modified zope install with my own /etc/init.d/zope and
/usr/sbin/zopectl.  I don't believe the problem is with this since the
processes restart just fine.

I would welcome suggestions on how to debug this problem.

At this point it just stalls, apparently indefinitely.

I'll hang around in #debian on Freenode for half an hour or so with the
nick kencausey.
