As reported by one of our users in this post: https://ml.mageia.org/l/arc/qa-discuss/2012-01/msg00004.html Trying to unsubscribe using the sympa webinterface results in an internal server error. To reproduce, visit https://ml.mageia.org/l/sigrequest/qa-discuss when not logged in to the sympa interface (not sure if this makes a difference) and try to unsubscribe by putting your email address and hit the link "Send me a validation link". You'll receive an internal server error (500). For bonus points, the webmaster address on the resulting error page points to the little helpful root@localhost address.
I can no longer reproduce this now as the website now says one has to be logged in first. Thanks for fixing it, whoever you are :-)
