Description
A user on our wiki uploaded the attached file on a page. Afterwards the file was listed twice in the attachments and we weren't able to delete the attachment nor the page itself. An error occurs in the log:

Trying to upload the file twice doesn't work anymore, so something went completely wrong with this attachment. There were no second user uploading something on that page, so he really edited it alone.
We are using the file storage and not storing it in the DB.
