314409 - reconstructing URL from MIME text breaks identification of URL boundaries

Status: RESOLVED DUPLICATE of bug 5351

(Thunderbird :: Mail Window Front End, defect)

Description

[Mike O'Dell]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b5) Gecko/20051006 Firefox/1.4.1
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b5) Gecko/20051006 Firefox/1.4.1

when a URL crosses a line-break in an underlying email body, the viewer correctly splices it back together as a single string, but the underlining machinery which provides "click-to-open" on the URL stops at the break in the underlying text. this leaves the last piece of a URL non-underlined and if you click-to-open, only the underlined fragment is handed to the browser. the rest of the URL is ignored.

Reproducible: Always

Steps to Reproduce:
1.send yourself an email with a long URL which crosses a MIME line-length boundary
2.open the email
3.observe that only the first part of the URL is underlined
4.click-to-open
5.observe that only the underlined first part is given to the browser

Actual Results:  
only the part of the URL before the underlying line break is underlined,
and when clicked, only the first part (ie, the underlined part) is given to the browser

Expected Results:  
the entire URL should be underlined and handed to the browser.
this worked correctly in previous versions of Thunderbird.

Related to/duplicate of Core bug 5351?

Comment 2

[Mike Cowperthwaite]

That dupe is likely, but reporter mentions "MIME text breaks" -- Mike O'Dell, does this mean the message was sent quoted-printable, such that the URL appeared completely concatenated, all on one line?

Comment 3

here's one Seth - I guess there's an ancient bug as well.
Seth points out that mail.app is especially bad about generating these kinds of urls.

I've noticed a similar problem when getting messages with
  Content-Type: text/plain; format=flowed; delsp=yes
and a broken URL (with a trailing space) which is supposed to be removed.
The URL displays correctly -- that is, unbroken -- but the linkification only applies to the first part.

Per comment 0, comment 1 and comment 2, this does look like a duplicate of bug 5351 to me.
Feel free to reopen if I'm wrong with more information why.
