I'm a little surprised, that you aren't asked for input, while the
debonf frontend is running on your system...

Where does this progress bar come from? I don't know this
personally. Maybe this is part of the problem, because it may block
the interaction of debconf readline?

I'd expect, that 24829 opens some kind of dialog/readline with you, if
you cannot see this, it may be the center of the problem.

This time no debconf interaction, so it runs without problems.
Maybe you could check, where upgrading from 3.0.25-1 to 3.0.25-2 works
correct, if you install 3.0.25-2 via
dpkg -i /var/cache/apt/archives/privoxy_3.0.25-2_amd64.de
instead of using apt-get (which may use some external hooks).
Sorry, I'm still digging in the fog, since I cannot reproduce the
issue and do not fully understand, what goes wrong on your system...
