If you'll notice the '/' and the /home/csv610/.gvfs mounts are 
identical.  A quick google gets this:

----[ README ]
| gvfs is a userspace virtual filesystem designed to work with the i/o
| abstractions of gio (a library availible in glib >= 2.15.1). It
| installs several modules that are automatically used by applications
| using the APIs of libgio. There is also fuse support that allows
| applications not using gio to access the gvfs filesystems.
|
|
| The gvfs model differs from e.g. gnome-vfs in that filesystems must
| be mounted before they are used. There is a central daemon (gvfsd)
| that handles coordinting mounts, and then each mount is (typically)
| in its own daemon process (although mounts can share daemon process).
|
| gvfs comes with a set of backends, including trash support, sftp,
| smb, http, dav and others. More backends are planned.
|
| gvfs also contains modules for gio that implement hal volume monitors
| and the gnome uri-scheme handler configuration.
|
| There is a set of command line programs starting with "gvfs-" that
| lets you run commands (like cat, ls, stat, etc) on files in the gvfs
| mounts.
