If you go to the history of a page, and click on the version (15:52) you will see this one. If you then click on "Newer revision", you will see the Version (18:17). And if you now click on edit, you will not edit the Version (18:17), but version (15:52). The same bug, if you go to "Older revision". Martin Vogel
Please provide a link to the exact page on the exact wiki you are referring to, or exact step-by- step directions to reproduce the problem on a fresh mediawiki installation. Can you also explain what this has to do with Wikimedia's domain name servers? This bug appears to be filed on the wrong component.
I've reproduced this, and identified the problem somewhat, using [[meta:Trophees_du_Libre]] as an example under v1.4.5. It also occurs in 1.5alpha2. After following a "Newer revision" link from http://meta.wikimedia.org/w/index.php?title=Trophees_du_Libre&oldid=2803 , we get a URL like http://meta.wikimedia.org/w/index.php?title=Trophees_du_Libre&direction=next&oldid=2803 . The edit link is now http://meta.wikimedia.org/w/index.php?title=Trophees_du_Libre&action=edit&oldid=2803 , and seems to be based on the oldid value from the URL, instead of the current revision id of 4529. The current revision id is used correctly in the "Older revision" and "Newer revision" links correctly, and the displayed revision timestamp matches the retrieved revision. It's just the wrong revision.
I thought the previous explanation was a little vague. You are viewing revision A. The next and previous links use oldid=A and direction=prev/next. You click one of the links. Now you're viewing revision B. The next and previous links use oldid=B and direction=prev/next. Problem: oldid in the url is A From SkinTemplate.php: $oldid = $wgRequest->getVal( 'oldid' ); Thus the edit button uses oldid=A and you get the revious before/after the one you were watching.

please see also bug 3630: Older revision is triggered by oldid value not by date - probably historical issue

Still a problem, as the edit this page apparently gets from the url rather that report the previous id; However, if you add the &direction=prev to the url, it seems to fix it. From: http://en.wikipedia.org/w/index.php?title=Template:Did_you_know&direction=prev&oldid=25242342 Edit this page points to: http://en.wikipedia.org/w/index.php?title=Template:Did_you_know&action=edit&oldid=25242342 Can be easily fixed if you add the &direction=prev ---- http://en.wikipedia.org/w/index.php?title=Template:Did_you_know&action=edit&direction=prev&oldid=25242342
Bug 4035 is related to this bug
Created attachment 1120 [details] Fix for HEAD * (bug 1915) Fix edit links when 'direction' used with 'oldid'; using revision ID reported via OutputPage; Skin::editUrlOptions() * Remove obsolete 'redirect=no' on some edit links * Include oldid for the second revision on edit link on diff view Committing this; it relies on other recently made changes on CVS HEAD which propagate the actual viewed revision ID up to OutputPage, so won't apply on REL1_5.
Apperently, the fix for this bug causes an oldid to be included in the edit link even if you are viewing the current version. I.e. if you click "edit" on a "normal" page view, you will edit the revision that was current when the page was rendered, not the version that is current when "edit" is clicked. This may or may not be The Right Thing... I seems to confuse people and cvause unintentional reverts. This is especially true for past cahning pages of course - like the village pump, etc. Please re-think this, people in the de:wp are complaining. See [[de:Wikipedia:Fragen_zur_Wikipedia#Was_ist_denn_jetzt_los??]] (german) for example. Apperently, this needs further discussion. re-opening.

I'm pretty sure I tested that, whoops...
