Apparently, some script on sigtrap.guug.de has been messing around with the file ownership of the CVS history file, leading to problems with anonymous CVS, and to empty snapshot tar-balls. I have corrected the history file for now, and generated new snapshots, which are available under /pub/mutt/snapshots/ from ftp.mutt.org. I hope the underlying problem will be fixed soon. Sorry for the inconvenience, tlr
