[Mailman-Users] UnicodeDecodeError with Mailman 2.1 and Python 2.6

[David Magda]

[Not sure if my first attempt made it out.]

Hello,

We recently upgrade from Debian 5 to 6, and are now having issues with
Mailman. Messages are still flowing properly, but the web archives are not
being generated since the upgrade.

When I run 'bin/arch mylistname' I get the following:

We're running 2.1.13, but as you can see, the problem persists even with
the latest release. We're using the stock Debian Python (2.6.6), but
Mailman for tarballs.

Thanks for any info.

Regards,
David
