[gtk+] mount-operation: don't show the dialog until the tree is populated

[Cosimo Cecchi <cosimoc src gnome org>]

commit d2540893086c46bad4c12071d31dfe86750949fe

    mount-operation: don't show the dialog until the tree is populated
    
    Otherwise it won't show up properly, and GTK+ will trigger a warning.
    Don't know why this did not show up before.
