E.g. see [[commons:File:Kassari mõisa valitsejamaja.jpg#filehistory]] or
[[commons:File:Vana-Põltsamaa mõisa aia_piirdemüür.jpg#filehistory]]. There are
multiple versions uploaded at the same time. As revision history for both
mentions no new versions uploaded (though upload log does), I assume these
files were uploaded at once.

Those aren't the same title...

These are two different examples. See the file history for either. Under first title there are two images (not sure what's the third item) and under second title there are two images.

UW does allow you to upload two different files with the same name -- it gives you a popup warning, but allows you to continue anyway. You're then asked to title the images.

Providing the same title isn't identified immediately, a "2" is apparently added, though. Providing the same should provide a JS warning and dis-allow continuing.

Doesn't appear to be a UW problem.

I still see this happening at [[commons:File:Lootsi_14.jpg#filehistory]]. Note there's a different image upload as new version, but without the usual "<username> uploaded a new version of <filename>" entry on history page. How comes it isn't a UW problem, if the 2 different photos can't be uploaded at once using the regular upload form and if according to comment line these images were uploaded using UW? Maybe it has got something to do with campaigns' part of UW. Software shouln't allow this, as one of the two photos is practically lost (without picking the older version and reuploading it).

Pikne: Please file a new bug report. This one was closed two years ago, and it's likely a different problem in the code nowadays.

Well, I don't know the cause, but the problem is the same, that I reported two years ago. This was probably never fixed other than mistakenly marked as a duplicate.

This does appear to be the same problem, but may not have the same cause.

The examples in comment #0 don't include the comment "User created page with UploadWizard". I don't know if this is significant -- maybe the comment was added later to the UW code -- but it is a difference.
