[Mailman-Users] Crash when adding subscribers

[Jean-Marc V. Liotier]

After having having installed the Mailman package on my Debian
(unstable) system and having completed the Postfix integration recipe
described in README.POSTFIX.gz, I created a couple of list (the
mandatory "mailman" list and a "test" list) and started trying to add
subscribers. The text I pasted below is the page I get after having
added one subscriber to a list using the Web interface to Mailman. I
tried adding subscriber using the command line, but the result is
similar. I have no idea where to start the debugging : I have a very
stock Debian system and I wonder what can cause such a crash. If
somebody could give me a hint to get me started, I would be grateful.
