[orca/570658] Handle case where parent == None

[William Walker <wwalker src gnome org>]

commit b98e2808804350c3fe4b1d3c092db6dffcf9d857

    Handle case where parent == None
    
    This came up when testing the horrible combobox on the Orca WIKI.
    The combobox on the WIKI is useless (we cannot get to the data),
    but this at least prevent tracebacks when dealing with it.
