enable accessability in gtk+ applications checkbox causes lxde to hang at startup

[Lyn Perrine]

I am reporting this from openbox as lxde hangs after this but to reproduce it in lxde. FIrst isntall a screenreader by sudo apt-get install gnome-orca or whaterver method you prefer then open lxappearance also known as customize look and feel in the menu. Then click on the tab at the top for other and the button on the bottom that says enable accessability in gtk+ appliactions. Note this is a new feature added in lxappearnce that is not in utopic or earlier.

I expected this to have a new working screen reader working with lxde. Instead the system seemed to hang at startup.
