checkbox-0.5 update does not update silently

[Bariki]

Binary package hint: checkbox

Running apt-get update && apt-get upgrade on my Alpha 4 amd64 desktop this evening yielded this little gem - checkbox whined about the package's config file not passing debconf's validation.

Setting up checkbox (0.5) ...
*** WARNING: ucf was run from a maintainer script that uses debconf, but
             the script did not pass --debconf-ok to ucf. The maintainer
             script should be fixed to not stop debconf before calling ucf,
             and pass it this parameter. For now, ucf will revert to using
             old-style, non-debconf prompting. Ugh!

             Please inform the package maintainer about this problem.
Configuration file `/etc/checkbox.d/checkbox.ini'
 ==> 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
      S : show the side-by-side differences between the versions
      Z : start a new shell to examine the situation
 The default action is to keep your current version.
*** checkbox.ini (Y/I/N/O/D/Z) [default=N] ?

Not having a clue what this meant I used Ctrl + C to quit that and come back to it later.
