bug#25820: 25.1; report-emacs-bug can't send mail due to missing 'w3'

[frederik]

I tried to report a bug using "report-emacs-bug". Emacs asked for a
method for delivering mail and I typed "mail" which it completed to
"mail client". But when I tried to send the bug, it complained that "w3"
was missing:

browse-url-w3: Cannot open load file: No such file or directory, w3

I have a working "mail" command which I had understood to be somewhat
standard on Unix, so I had wanted to send the report via this method.
Thank you.

I can sort of perhaps see why you would choose "mail client" wanting to
get such a result, but you want "sendmail" instead.

The only way I can see that this can happen is if you have customized
browse-url-browser-function to browse-url-w3, and don't have the w3
library installed. So please tell us what 

C-h v browse-url-browser-function RET

says for you. If it does say browse-url-w3, then that's a bug in your
configuration.

Thank you. Yes browse-url-browser-function was set to browse-url-w3 in
my ~/.emacs.

Thank you for telling me which send-mail-function I want.

It would be nice to have things like this work "out of the box", but
maybe most GNU/Linux are not set up to have a working 'mail' function
anyway. Anyway, thanks for looking at the bug report.
