Bug#241957: woody to sid apache upgrade hang

[Bill Allombert <allomber@math.u-bordeaux.fr>]

Package: apache
Version: 1.3.29.0.2-4
Severity: important

Hello Debian Apache maintainers,

During the latest woody to sid upgrade test I performed (under
user-mode-linux, the upgrade process get stalled:

Setting up apache (1.3.29.0.2-4) ...
Configuration file `/etc/apache/httpd.conf'
 ==> File on system created by you or by a script.
 ==> File also in package provided by package maintainer.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a new shell to examine the situation
 The default action is to keep your current version.
***  httpd.conf  (Y/I/N/O/D/Z) [default=N] ?

Whatever optionI choose, the upgrade process hang.
Doing a ^Z and ps auwwx I get:

root      6926  0.0  2.8  8836 7228 tty1     T    18:17   0:00 apt-get install apache-common
root      6930  0.0  7.0 19292 17808 tty1    T    18:17   0:00 /usr/bin/dpkg --configure apache

/usr/share/debconf/frontend /var/lib/dpkg/info/apache.postinst configure 1.3.26-0woody3
root      6938  0.0  0.5  2480 1288 tty1     T    18:17   0:00 /bin/bash /var/lib/dpkg/info/apache.postinst configure 1.3.26-0woody3
root      7890  0.0  0.4  2400 1208 tty1     T    18:17   0:00 /bin/bash /usr/bin/ucf --debconf-ok /etc/apache/httpd.conf.dpkg-inst.queue /etc/apache/httpd.conf

So maybe it is related to ucf/debconf.

There is the definite possibility I have a poorly configured
user-mode-linux system, but I perform regularly such upgrading test and
it is the first time it hangs there.
