I received the following error message, which is wrong:

"The file you uploaded seems to be empty. This might be due to a typo in the
file name. Please check whether you really want to upload this file."

However the file was not empty, I had simply waited too long to press "save
file" on the "warning" screen after uploading a file which already exists
(giving the option to "save file" or "re-upload"), and the image was presumably
automatically deleted from server.

The message should be changed as follows:

"The file you uploaded seems to be empty. This might be due to a typo in the
file name, or because a warning screen timed out. Please check the file and try
uploading it again."

A more complex solution would be to tailor the message accordingly, depending on
which path lead the user to the error.
