Please describe the problem:
I've been playing around with FUSE, which is pretty neat, but Nautilus' thumbnailing is causing problems.  

First, I set up an encrypted ~/vault directory, using encfs, but I can't find a way to stop Nautilus from thumbnailing the contents of it, and storing those thumbnails in the unencrypted ~/.thumbnails.  Obviously this rather reduces the value of an encrypted directory. 

Second, I tried mounting a remote drive using sshfs, which works great, but Nautilus tries to thumbnail the contents of that too, even though it's mounted over a slow connection.  This is also problamatic.  

I gather the normal way of dealing with this is to mark certain filesystems non-local in gnome-vfs, and I suppose that could work here, as long as you can tell different kinds of FUSE filesystems apart.  In any case, I don't have any better ideas.

Steps to reproduce:
1.  Mount filesystem
2.  Open in Nautilus


Actual results:
Nautilus thumbnails the contents of the directory, even if it is remote or contains sensitive encrypted documents.

Expected results:
Nautilus doesn't thumbnail the contents of the directory if it is remote or contains sensitive encrypted documents.

Does this happen every time?
Yes.
