It's a virtual filesystem, used by gnome. It doesn't implement everything stat() wants to get so it returns an error. Here is a quote from Fedora mailing list about a similar problem:
The issue is that when the user is
logged in, fuse creates a memory
resident filesystem interpreted by the
user process.
This user process doesn't implement
anything but owner. All else is
refused. Root can't access it because
it isn't the owner, and can't override
that because the fuse filesystem
doesn't implement/support the
override.
