Thanks for mentioning this in bug 54776, I had seen the summary in my search results but I thought it was another thing (the bug I just duplicated to this).

Would it be possible to check a Commons dump to see how often this occurs? It should be detectable as a upload over an existing file with the edit comment "User created page with UploadWizard" [1]. Since the wizard does not allow re-uploading this should only ever occur in this case.

Note, potential dupe at bug 64883 (But this one was here first).
