bug#17613: 24.3; html2text can't handle weird formatting

From: Mark A. Hershberger
Subject: bug#17613: 24.3; html2text can't handle weird formatting
Date: Tue, 27 May 2014 19:14:04 -0400

I got an email today whose source includes:

                                <a class=3D"mcnButton " title=3D"Profile L=
ink" href=3D"http://secret................................................=
...................................................." target=3D"_blank" st=
yle=3D"font-weight: bold;letter-spacing: normal;line-height: 100%;text-ali=
gn: center;text-decoration: none;color: #FFFFFF;word-wrap: break-word;-ms-=
text-size-adjust: 100%;-webkit-text-size-adjust: 100%;">Create Your Profil=

Line breaks exactly as they are in the email's source.

mu4e is being used to parse and display the email.  In
html2text-get-attr, execution stops on the following code:

       ;; size=3
       ((string-match "[^ ]=[^ ]" this)
        (let ((attr  (nth 0 (split-string this "=")))
              (value (substring prev (1+ (string-match "=" this)))))

with the message:

    Args out of range: "\"", 6, 1

describe-variable for this says:

    this's value is "title=\"Profile"

The html I've posted above is the only place where 'title="Profile' is
in the email.
