Hello all,
I've noticed some unusual behavior with repeating entries when the
system-time-locale variable is set. Specifically:
It is Sunday, today, October 30th. I did not mark this task, which is
a habit, yesterday.
-- If I have (setq system-time-locale "hu_HU.utf8"), Hungarian, then
marking this task DONE
* TODO Anki basic reviews :habit:study:
SCHEDULED: <2016-10-29 szo .+1d>
v----becomes----v
* TODO Anki basic reviews :habit:study:
SCHEDULED: <2016-10-30 v .+1d>
Which is not correct. I marked it DONE today, so it should repeat tomorrow.
-- If I have (setq system-time-locale "es_MX.utf8"), Mexican Spanish,
then doing the same thing:
* TODO Anki basic reviews :habit:study:
SCHEDULED: <2016-10-29 szo .+1d>
v----becomes----v
* TODO Anki basic reviews :habit:study:
SCHEDULED: <2016-10-31 lun .+1d>
Which *is* correct. I have tried this with an unset
system-time-locale, and with it set to fa_IR, es_MX, en_GB, and hu_HU.
So far, hu_HU is the only one that behaves incorrectly. Note that it
doesn't seem to matter which language the day-of-the-week abbreviation
is already in, since every time I tried this, I reverted the file back
to the Hungarian line. Changing the date to <2016-10-29 Sat .+1d>
before marking it also had no effect.
Of course, I could just set the date locale to "C" or unset it, but
there's still a bug somewhere.
I am running the 1399f5 revision now, but I can reproduce this
behavior all the way back until version 7,
Cheers,
Bruce V C

I tend to think this is not a bug in Org mode, since it correctly work
with other locales, and we do not control locales.
Anyway, could you try bisecting and tell us when the bug was born?

I thought so too, to be honest, but I got my hands dirty and I think
I've figured out where the actual problem lies.
I did the bisect earlier, and the breaking change was right when the
code to handle native language day names was added as part of Org 8.0.
I got a bit disorganized and lost the exact commit, but I can try to
find it if need be. Anyway, I started the lisp debugger to trace what
was happening and found the real problem. I hope someone can confirm.
org-todo calls org-auto-repeat-maybe, which sees the ".+" style
repeater. It calls org-timestamp-change to move the timestamp up to
today. Point is left at the closing bracket. So far, so good.
org-timestamp-change sets origin-cat to 'after and origin to (point).
It then changes the timestamp to today as advertized.
Now these lines get evaluated
(goto-char (cond
;; `day' category ends before `hour' if any, or at
;; the end of the day name.
((eq origin-cat 'day)
(min (or (match-beginning 7) (- (match-end 5) 2)) origin))
((eq origin-cat 'hour) (min (match-end 7) origin))
((eq origin-cat 'minute) (min (1- (match-end 8)) origin))
((integerp origin-cat) (min (1- (match-end 0)) origin))
;; `year' and `month' have both fixed size: point
;; couldn't have moved into another part.
(t origin))))
The since origin-cat is 'after, matching nothing else, we get
(goto-char origin).
This seems to be where the problem lies. When "<2016-10-29 szo .+1>"
becomes "<2016-10-31 h .+1>" (today), origin is now two characters
ahead of where it should be, now on the next line in fact.
So it returns fine at first, but when org-auto-repeat maybe calls
org-timestamp-change a second time to move the date into the future,
it throws the error "Not at a timestamp" and does nothing else. I
wasn't seeing this error until I was in the debugger, since
org-auto-repeat-maybe puts an "Entry repeats: ..." message in the echo
area. Oddly enough, that message shows the correct date since
org-last-changed-timestamp gets updated properly.

I see. Thank you for the analysis.
Does adding the following branch in the `cond' above, before the
catch-all one, solves the issue?
((eq origin-cat 'after) (match-end 0))
