That's awkward, I tested localization several times during the
development cycle of apt-listbugs/0.1.10 and I have never found any
issues (even with German localization).

Anyway, the localization is handled by ruby-gettext and ruby-locale:
apt-listbugs itself does not directly manage the locale environment
variables or the encoding names.
I am hence reassigning your bug report to ruby-locale, as I think the
error is generated by that library (or maybe by ruby-gettext?).

I see that you set some locale environment variables to "de_DE.utf8".
Shouldn't it be "de_DE.UTF-8"?

I've just checked with

  # LC_ALL=de_DE.UTF-8 aptitude install some_package

and both aptitude and apt-listbugs ran correctly with output in German.
Please try and set your locale to "de_DE.UTF-8": it should make
apt-listbugs work correctly.

I also tested

  # LC_ALL=de_DE.utf8 aptitude install some_package

The awkward result is that aptitude seems to run correctly with output
in German, while apt-listbugs fails with the error you experienced!
Maybe there's some Ruby-specific peculiarity (or bug!) in the locale
handling that prevents "de_DE.utf8" from being accepted as a valid
setting (apt-listbugs is written in Ruby, while aptitude is not!).

I hope the maintainers of ruby-locale / ruby-gettext will soon figure
out what's wrong...

Bye.
