[Message part 1 (text/plain, inline)]

--text follows this line--

On a windows 7 machine, I used the emacsclientw.exe program to edit a
file -- I associated the client with the file type and double clicked
the associated file.  The emacs server was running, and a window popped
up visiting the file I had doubleclicked.
At this point everything is fine.  I left-clicked the mouse on the
"Server" minor mode indicator in the mode line, and selected "help for
minor mode".

At this point a buffer popped up in a new emacs window, containing the
following:
-----------begin buffer contents on next line----------------------
server-buffer-clients is an alias for `server-buffer-clients',
which is not defined.  Please make a bug report.
-----------end buffer contents at end of previous line-------------

Thanks for the report. I don't think this ("help for minor mode") has
ever worked for "Server". The thing that server.el adds to
minor-mode-alist is not a real minor mode.
minor-mode-menu-from-indicator tries to call
(describe-function 'server-buffer-clients), which fails. But in 24.4 it
fails in a new way.

I think there are 2 (or maybe 3) bugs here:

1) A problem with describe-function, new in 24.4:

(describe-function 'not-defined)

24.3: -> Symbol's function definition is void: not-defined   # fine
24.4: -> 
  not-defined is an alias for `not-defined',
  which is not defined.  Please make a bug report.


2) server.el adding something that is not a minor-mode to minor-mode-alist.


3) minor-mode-menu-from-indicator lack of error trapping for when
describe-function fails.


1) definitely needs to be fixed.

This is due to symbol-function no longer returning an error.
It would be good if someone could fix this for 24.5.
Probably describe-function-1 just needs an fboundp check at some point.
