Fix Red Hat bugzilla bug : https://bugzilla.redhat.com/show_bug.cgi?id=516165
nautilus fails to copy files from an SMB share. This is a show-stopper
for 3.4.1 (I'll open a Samba.org bug). Although gnome-vfs is doing
*incredibly* stupid things by asking for a read size of 65535 - this
translates on the wire to a 65534 byte read followed by a 1 byte
read. Please send this back to the gnome developers that they
will ge horrid on the wire performance for this.
