When I see Media Library via webdav in french, it is translated to "Média" (with accent) and showed as a folder. When I go inside "Média", folders are showed as files.

For some reason, it's buggy because of accent in translation. You can find a quick fix in attachment for kernel/private/classes/webdav/ezwebdavcontentbackend.php.

When I remove translation, "Média" comes back to "Media" and media library is accessible correctly : folders are shown as folders, etc

Steps to reproduce

Just browse with webdav in a french website
