mutt problems after recent sid upgrade

[Lee Bradshaw <lee@sectionIV.com>]

After upgrading two machines (first one Saturday, and second one
yesterday), mutt no longer works. When started on the console it
segmentation faults, and when started in a gnome-terminal it seems to
try to grab more memory until it is killed. mutt itself wasn't upgraded
- it remained at version 1.4.0-5 during the upgrade. I've tried several
easy things - remove and reinstall, build the deb package myself and
install that - but the upgraded systems won't run mutt. Evolution and
elm seem to work ok, but I'd rather use mutt. Any ideas what the problem
is?
