Description:
Hello,

we hit a strange result on fr.wikipedia.org. We are
wondering if this is not a database corruption.

As this link ( http://fr.wikipedia.org/w/index.php?
title=Wikip%C3%A9dia:Wikip%C3%
A9diens_par_sports&diff=prev&oldid=1614426 ) shows, there
is an incoherence in the timeline of the modification
history.

I don't know if it is a real threat or not, so I have
protected the page for any other modification until
further information.

It would be nice, if somebody could look into it in order
at least to tell us if we can remove the protection or if
some maintainance on the DB must be done.

Thank you in advance

JYP, admin on fr.wikipedia.org

The 'next' and 'previous' links in the history are very unreliable in the case of pages which have had histories merged via
deletion/undeletion.

Did something like that happen on that page?

The earliest listed revision:
http://fr.wikipedia.org/w/index.php?title=Wikipédia:Wikipédiens_par_sports&oldid=1614426

Fits very well by diff against the next listed revision:
http://fr.wikipedia.org/w/index.php?title=Wikipédia:Wikipédiens_par_sports&oldid=1311881

but has a later old id number, which is often an indication of merging.

As far as I know, no: we didn't do anything special (deleting, restauring) on
this pages.

If we look the history, everything looks fine.
Question: is it safe to unblock this page for further use?

Looks like bug n°2219 reports the same problem.

The same problem occurs on another article in the French WP : see this diff
http://fr.wikipedia.org/w/index.php?title=Andr%C3%A9e_Brunin&diff=next&oldid=1448234
compared to this one :
http://fr.wikipedia.org/w/index.php?title=Andr%C3%A9e_Brunin&diff=next&oldid=1595425

The dates seem to be incorrect.
