This may be an upstream bug. I pulled in the emacs 24.5 source and compiled it. I do not see the appointment notifications on it.
wget http://ftp.gnu.org/gnu/emacs/emacs-24.5.tar.gz Also, testing in terminal mode ("emacs -nw") does not produce the notifications. -- The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized. -- U.S. Const.
