emacs-w3m-1.5-alt0.1.20120203 It works with emacs23, but with emacs24 from Sisyphus, M-x w3m can't run because it requires a missing library: auth-source. I could find it in emacs24-gnus. (BTW, after that, I still couldn't use emacs-w3m with emacs24 successfully, because of the bug when trying to edit a textarea in bugzilla, already reported.)
Fixed in 24.5-alt15 and up.
