[mew-int 2461] Bug in mew-browse-url-at-mouse with w3m

Fri Apr 18 14:56:09 JST 2008

This is a bug that has been annoying me for years, across several
versions of emacs and mew. I've finally taken the time to reproduce it
in a minimal environment.

The symptoms: I receive a mail that is Text/Html in
Multipart/Alternative. It contains a link of the type <a href="url">here</a>.

I mouse-2 click on the link, and mew hands "here" to the browser,
instead of "url".

Exact action:

1) Start up emacs without arguments

2) In emacs, type "\M-x mew <CR>"

3) Move to (only) message in inbox

4) type "." to display message. Shows "here" in blue indicating
   link. Moving the mouse over "here" shows the URL "http://nicta.com.au/".

5) Click middle mouse button on link. Browser starts up, displaying a
   "server not found" message and "http://www.here./" in the URL
   window.

This is run in an as-close-as-possible vanilla environment. Emacs
version is 22.1.1 on Ubuntu, Mew version is 5.2 (but as I said, I had
the same with older versions of emacs and mew). All other relevant
stuff below:
