Description

Author: sp23qst

Description:
On http://fr.wikipedia.org/wiki/Discussion:Élie_de_Bourbon-Parme the history page as consulted yesterday or today contains only two versions, the latest, from December 2007 (the one referred to by the URL http://fr.wikipedia.org/wiki/Discussion:Élie_de_Bourbon-Parme ) only contains a self-redirection.

Other versions (most of them indeed) can be found in their author's contributions pages, and reached using their oldid parameter. See http://fr.wikipedia.org/w/index.php?oldid=42838065 and previous versions (reachable from the one given). They seem not to belong to any History page.

Seemingly, the problem has appeared recently ; the series of versions today hard to reach (only through the User's contributions pages as far as I know how to look for them) was last modified on July 10th.

The same flaw was met on http://fr.wikipedia.org/wiki/Charles_III_de_Parme (and its Talk page) and http://fr.wikipedia.org/wiki/Élie_de_Bourbon-Parme but is a bit less obvious to understand on these two examples since rudimentary ad hoc fixes (copy-paste, suppression/recreation, moves,...) have been experimented later and somehow can hide the problem under recent edits. Note that on the article "Élie_de_Bourbon-Parme" the last version lost from Histories is dated from September 3rd : seemingly the problem happened only later than this date.

Same problem as bug 20741 (  silently changed to space). Should be fixed soon (day or two?).
Increasing numbers of reports coming in, the change happened during code update 3 days ago.
