Hi,
i noticed that when using the org-mode clock persistence, the stored
clock data gets deleted when i start emacs and exit again without
turning on org-mode in between.
When looking at org-clock-persistence-insinuate it looks like org-clock
load will only run after org-mode gets started whereas org-clock-save
will always be called when exiting emacs:
(defun org-clock-persistence-insinuate ()
"Set up hooks for clock persistence"
(add-hook 'org-mode-hook 'org-clock-load)
(add-hook 'kill-emacs-hook 'org-clock-save))
Not running org-mode-hook (i.e. not starting org-mode) thus does not
load clock data but org-clock-save overwrites any prviously saved data
when exiting emacs.
An easy fix for that would be to just add org-clock-load to e.g.
emacs-startup-hook. But this will only work if the code in
org-clock-load does not depend on any org-mode initialization code (or
would require loading org-mode).
So org-clock-save should probably check if org-clock-load has been
running during the current emacs session (or if clock persistence was
just enabled) and only then save clock data when exiting emacs. I tried
to add this to the code in org-clock-save:

I see you point, but I am not convinced that you fix is the right
one. What one really wants to do is save the clock and history if and
only if the clock has been used in the current session. So I guess it
is better to create a special variable org-clock-used-in-this-session
which then will be set to t each time clock-in starts a clock
somewhere. I believe this would be a better insurance policy.
Would you like to try your hand at a patch in this spirit?

You're right - this would be even better.

I've just started to play with emacs lisp. But this sounds like
something not too difficult. So thanks for the offer :-), i'm going to
give it a try ...

Ok, i've attached a new path which uses the suggested approach. I wasn't
exactly sure about where to set org-clock-used-in-this-session to t.
It's now done right at the end of org-clock-in, just before running
hooks in org-clock-in-hook.
I've done a couple of (simple) tests and it works fine for me.

Hi Kai,
after giving it more thought, what I checked in is actually
a combination of the two patches you sent.
Thanks you for finding and fixing this issue.
