nil("mailto:sran...@gmail.com; (nil))


when `browse-url-mailto-function' is set to nil. However docstring to
this variable allows nil (perhaps there is really an Emacs bug). Now I
am puzzled why setting `browse-url-mailto-function' to
`browse-url-default-browser' does not help. I have no idea what should
be suggested to users instead of nil.


This is Emacs bug that should be reported.
I do not think that we need to document every workaround for Emacs bugs.
Especially given that Emacs 29 is just around the corner.


Debian bookworm (that is about to be released) has Emacs-28.

It is preferable to have a link clearly describing a workaround, at 
least to a specific comment at debbugs. However I believe, it is better 
to describe a recipe in Org FAQ and to retain users from customizing 
`org-link-parameters' if no web page may be suggested instead.


Anyway we do not have a workaround yet.

I tried that yesterday and it didn't work.


It is strange taking into account `browse-url-default-handlers'. I am 
curious what happens in response to


(browse-url-default-browser "mailto:sran...@gmail.com;)

I've spent some time looking through the code of browse-url.el, and I've been 
unable to alter its code so that setting `browse-url-mailto-function' to 
`browse-url-default-browser' works. But my grasp of Elisp is not good. I'm 
going to make a detailed bug report as soon as I can find the time to make it.

I agree, I've looked through the code of browse-url.el in 28.2 and 27.2 (where 
it works) but I can't find the problem because my understanding of Elisp is 
primitive. I've never reported an Emacs bug before, but I will try.

Then, it looks like mis-configured `browse-url'.
Check your configuration.



Here are some steps I tried following your advice.

(1) I eliminated all customizations that involved `browse-url' from my 
configuration and restarted Emacs (Emacs 28.2, Org 9.6.6).

(2) I executed (browse-url "mailto:sran...@gmail.com;) and the buffer to edit 
an email appeared.

(3) I executed (browse-url "https://orgmode.org/;) and the Org Mode site opened 
in Firefox.

(4) I executed (customize-set-variable 'browse-url-mailto-function nil) and then executed 
(browse-url "mailto:sran...@gmail.com;). The result gave the same error 
messages.

(5) I quit Emacs and ran `emacs -q' (Emacs 28.2, Org 9.5.5).

(6) I executed (browse-url "mailto:sran...@gmail.com;) and the buffer to edit 
an email appeared.

(7) I executed (browse-url "https://orgmode.org/;) and the Org Mode site opened 
in Firefox.

(8) I executed (customize-set-variable 'browse-url-mailto-function nil) and then executed 
(browse-url "mailto:sran...@gmail.com;). The result gave the same error 
messages.

I'm not sure how my configuration can be at fault when `emacs -q' gives the 
same result. I'm not sure what to do now.
