I can confirm the issue brought up my eZ forum user Nicklas Lundgren (http://share.ez.no/forums/developer/webdav-and-ez-4.1.1-404-error) regarding nothing to see under the 'Media' folder using webdav.

I'm using Apache 2.2.9, eZ 4.1.3 and PHP5.2.9 and successfully connected to one of my siteaccesses and can view the contents of the 'Content' folder via webdav, but clicking on 'Media', nothing is shown.

I have tried the following clients with the same results:

Konqueror 4.1.3 (On Linux FC9)
WebDrive 9.1 (On Win XP SP3)
NetDrive 1.0.8.15 (On Win XP SP3)

Steps to reproduce

Connect to a siteaccess and use the admin login credentials to authenticate in your WebDAV client. Default folders are always 'Content' and 'Media'. Try viewing the contents of 'Media' - nothing shown, no errors logged even though there are folders and pdfs and images in my 'Media' folder and the 'Media' folder has the section 'Media' associated with it.
