    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. 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.
    Jeremy.
    
    Fixes bug #6649.
    
    Fixed in master with commit 33d27797d3ae9ab3ff7e1aa940941cc450f5ad1d.
