Who thought this was a good idea to automate?
And how does one get this fixed? I can't even revert to a good copy.
Has a list of these been made and human-checked?

I can't answer to the automated or not part, partially because I'm missing the rest of the thread. I can tell you that because our one server with the thumbs on it was getting dangerously low on space (and still is), I've been purging a number of thumbs each day that are not linked to on our projects. People viewing those images again get new thumbs, with whatever side effects that entails.
I've been asked today by some commons folks to filter out all images with certain exif orientation data in it from the list, so I'm looking at that right now. If the percentage is small enough I'll do that, though this does not resolve the problem in the mid or long term. Thumbs are meant to be temporary data; we should not rely on any given thumb or set of thumbs remaining around forever.

Me -- most of the time that's the correct thing to do. Problems generally only show up when someone managed to damage an individual image by rotating it in an image editor that, somehow, preserved all the EXIF data without updating its orientation info.
Since you uploaded it, can I ask what you used to process the image before uploading it that might have left it in this state?
(And yes, we know that allowing you to preview & fix the rotation *during* the upload process will be a big help. There should be a bugzilla entry ready for comments somewhere.)

There's a rotation bot that will fix things up for you -- it was already fixed up to understand our new auto-rotation treatments a few weeks ago.

At the moment it's listed as stuck, don't know what it needs jostled.

As noted in the image, just jpegtran, set to preserve EXIF. I suppose that was asking for trouble.
(grumble, mutter, the software should read my mind better)

In this case, the problem is an old image being fixed wrong.
Perhaps some sort of editable setting, there in the image page, so anyone who sees an inappropriately-rotated image can fix it? I have a nasty feeling that, with the help of jpegtran, I'll have uploaded quite a few images that will do this ...

*nod* I'd love nice big "rotate left", "rotate right" buttons or something, both during upload preview and when looking at / modifying an existing photo.

There's a "(request rotation)" link at the right of the MIME which provides a nice dialog for that. It's provided by RotateLink Gadget.
According to its description page it "is enabled by default for all logged-in users" http://commons.wikimedia.org/wiki/Help:RotateLink

It's listed as enabled in my preferences, but no such link is visible on the image in question.

Well, it looks like automatic image rotation is not as good an idea as Brion and I originally thought. Do people think we should remove the auto-rotation (i.e. set $wgEnableAutoRotation = false) until we have something in MediaWiki to rotate images?

Brion's point that it's likely to hit only people like me who do perverse things strikes me as, in fact, likely ... but is there a lighter-weight way to do it? e.g. tell MediaWiki what rotation to produce the thumbnail at, and make this easily user-overridable? This avoids having to do transforms to the actual image or mess with the file.

I expressed my opinion on https://bugzilla.wikimedia.org/show_bug.cgi?id=31504#c6 two months ago. Now there may be some "looking good only due to EXIF" images, though.
It might have been better to have a policy to grandfather in old images. So if an image was uploaded prior to the introduction of automatic EXIF rotation, it wouldn't be auto-rotated. But at this point where it's a bit mixed up, I'm not sure how to fix the situation with older images.
EXIF rotation should be the default for any new images, however.
Perhaps we need a button which can do rotation in the same way as submitting a modified wiki article.

I couldn't find one, so I opened one:

Since most desktop image software these days silently rotates images on display using EXIF orientation field, and MediaWiki until now didn't, a lot of users have been complaining that their uploaded photos display in the wrong orientation. Going forward the change should probably reduce unexpected behavior, but yeah, there seems to be a big backlog of wrong-oriented images now that assumed the previous behavior...
