TYPO3 Core

Everytime a file which has '@' somewhere in the filename is used in the frontend, a warning is logged in /var/log/typo3_something.log:

I can reproduce this by uploading a file named "öäüß€-_#'!§$%&()=.png" which gets renamed to "oeaeuess@EUR-____________.png" after the upload. Note the is the only character that still remains.

You can open the preview directly in the filelist module, and you can add the image to an image content element as usual. The image is then shown in the frontend without an error, but said warning is logged in the logfile.

If I remove the @ from the filename no warning is logged.
