Not sure what's wrong here. Deletion of individual file revisions should be the file deletion page, not the revision deletion page.

Or am I misunderstanding something?

I just encountered a strange behaviour, from what I understand it's the same as what Robert reported, only phrased differently. When trying to delete a single revision of a file, using the "delete" link for this revision in the "File history" section of the description page, I inadvertedly deleted all the revisions of the file and of the description page. Surely this wasn't the previous behaviour.

Just an FYI that it's also being discussed at the en.wiki [[Wikipedia:Village pump (technical)#Image/File deletion issue]].

The problem is with the "oldimage[]" parameter (or its interpretation):
It's generated as e.g.
http://en.wikipedia.org/w/index.php?title=File:Najib_Tun_Razak_cropped.jpg&action=delete&oldimage[]=20090405034831!Najib_Tun_Razak_cropped.jpg
however,
http://en.wikipedia.org/w/index.php?title=File:Najib_Tun_Razak_cropped.jpg&action=delete&oldimage=20090405034831!Najib_Tun_Razak_cropped.jpg
currently works.

Thanks Amalthea! The removal of the [] after delete&oldimage does the trick. I removed it in the address bar, re-sent the request without the [] and it did point to the correct page, which did solely the revision deletion. See [[File:1983worldjamboree.jpg]] and [[File:4C ecosa logo master copy.jpg]]. Is it possible to just have the [] removed from the command, or would that create other problems?

I can confirm the issue: when trying to delete an old revision of a file, the entire page gets deleted instead.

Fixed in: http://www.mediawiki.org/wiki/Special:Code/MediaWiki/48837

Note: not yet live, but apparently fixed, unless the fix gets reverted. Then bug should be reopened.

Since the fix is disputed in CodeReview and has not been deployed, I'm re-opening this for now.

r48837 is deployed on Wikimedia now, but for 1.15 I will revert r48277 and any related revisions instead.
