Recently, I've been getting email messages that look like this:

Am I seeing messages that are being sent from a buggy sender, or is my
local /usr/bin/w3m blowing up and spewing the detritus into the mail
message?

This is with w3m 0.5.3-31, which appears to be the most current version
in Debian testing.
