After a bit of struggle I was able to mount the Clix and see its contents with Nautilus (GNOME's filemanager), and with Konqueror as well.

To be able to see the contents of the Clix (and arguably also write to it) I was missing the option allow_other for fuse, so the mount command in this case was (as root):

If you have sudo active (Ubuntu), you may prepend 'sudo' (without the quotes) to the command above.

Here are a couple screenshots:

Nautilus:


Konqueror:


Now the challenge is to get an autofs configuration so when the clix is connected to the PC, it will be automounted onto a location based on device identifier (i.e /media/clix for a 1st gen Clix, /media/clix2 for a 2nd gen Clix, /media/zen for a Creative Zen, etc)... Still looking around. The above screenshots and configurations were made on a Fedora Core 6 box.
