This didn't produce any debug output, so I did a bit of digging and it 
looks like it was actually falling over in the debconf Gnome frontend 
... specifically ...

    require Debconf/FrontEnd/Gnome.pm called at (eval 
33)[/usr/share/perl5/Debconf/AutoSelect.pm:52] line 2

    eval {...} called at /usr/lib/perl5/Gnome2.pm line 0
    eval '

            Debconf::FrontEnd::Gnome->new();

Switching to Dialog fixed the problem.  I'm not sure if this is related 
to bug #443753 or if it's an entirely separate SEGV ;-)

Rgrds,
