Nautilus for webdav?

[Huub]

Hi,

Using DFBSD 1.9 with Gnome, I want to access a webdav disk. When I go to 
Places | Connect to Server, I can choose https (secure webdav) and 
create a connection. But when I want to open it, Firefox opens with the 
message it can't display anything because the protocol is unknown. How 
can I assign Nautilus to open up instead? I'd rather not use cadaver, 
since that's commandline only.

Thanks,

Huub
