------------------ Additional Follow-up Comments ----------------------------
Initial analysis shows that problem occurs when the
base URL of an HTML message is determined to be just
the protocol string (e.g. "http://";) and nothing more
(btw, this problem could technically affect readmail.pl
also).
In the sample message, the base is computed to be
"file://" -- that's it. Actually, the message uses
'' as path separator for the pathname compoent,
but that is not legal, and I have no desire to to deal
with it. Therefore, mhtxthtml.pl computes the base
URL (from the <BASE> tag) to just be "file://".
Regardless, a decision needs to be made on how to handle
cases where the base URL is bogus, like "http://"; (no
hostname component is present). At a minimum, the code
needs to so some integrity checks to avoid the Perl error
message. Trying to validate the URL may be a pain since
it would require knowing all possible URL schemes.
