I suggest you don't change your general locale settings (I mean, not
just for this bug, at least!).
Instead, I think you should temporary work around this bug, by editing
/etc/apt/apt.conf.d/10apt-listbugs, as I previously suggested, and wait
for this bug to be really fixed!
For reasons explained below, I think the workaround may be made even
less invasive: when you edit /etc/apt/apt.conf.d/10apt-listbugs , you
may change the line
DPkg::Pre-Install-Pkgs {"/usr/sbin/apt-listbugs apt || exit 10";};
into
DPkg::Pre-Install-Pkgs {"env LC_NUMERIC=C /usr/sbin/apt-listbugs apt || exit
10";};
This should be enough to temporary work around the bug, while letting
apt-listbugs speak in your language of choice!
Please test it out and see if it works...

It seems that the problem lies in the HTTP headers.
Please note that "HTTP/1,1" ...
It should be "HTTP/1.1" instead!
The HTTP version should be in integer-dot-integer form, rather than in
integer-comma-integer form.

You seem to access the Internet through a transparent HTTP proxy (named
nethsecurity.csa.lan on your local network).
The wrong HTTP header makes this proxy angry, causing it to close the
connection.
See also http://bugs.debian.org/92175 where a similar problem was found
in gweather, again behind a squid proxy.
So, in summary: the problem seems to be that, with some locales (where
the decimal separator is a comma, rather than a point),
libhttpclient-ruby1.8 creates wrong HTTP headers.
It seems to me that the HTTP header generating code is in
/usr/lib/ruby/1.8/httpclient/http.rb
Hence, I am reassigning the bug to the appropriate package.
Finally, I have to admit that I am still unable to reproduce the bug:
I've been trying to get that "HTTP/1,1" header in apt-listbugs debug
wire dump, but no success yet... :-(
This may mean that some other condition must be satisfied in order to
trigger the bug that Paolo is experiencing (maybe being behind a
transparent proxy is essential?).
I hope libhttpclient-ruby1.8 experts may pinpoint the bug and fix it
soon.
Bye.
