several packages failing -- is debconf broke?

[John Covici <covici@ccs.covici.com>]

I have had two packages fail on an upgrade -- here is the output from
the postinst script (I put set -v and set -x in it).

Setting up foomatic-bin (2.0.2-20021202-1) ...
set -x
# Source debconf library.
. /usr/share/debconf/confmodule
+ . /usr/share/debconf/confmodule
#!/bin/sh
# This is a shell library to interface to the Debian configration
management
# system.

# Initialization.

# Check to see if a FrontEnd is running.
if [ ! "$DEBIAN_HAS_FRONTEND" ]; then
        # Ok, this is pretty crazy. Since there is no FrontEnd, this
        # program execs a FrontEnd. It will then run a new copy of $0
        that
        # can talk to it.
        exec /usr/share/debconf/frontend $0 "$@"
fi
++ '[' '!' '' ']'
++ exec /usr/share/debconf/frontend
/var/lib/dpkg/info/foomatic-bin.postinst configure 2.0-20020911-0.4
dpkg: error processing foomatic-bin (--configure):
 subprocess post-installation script returned error exit status 20

I could fake it by putting exit 0, but what is really going on?

Thanks.
