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.
