Keyboard shortcuts on Shift+Alt+( and Shift+Alt+) do not work

Steps to reproduce:

1. Open GNOME Settings
2. Create a keyboard shortcut for Shift+Alt+9 (which can also be thought of as "Shift+Alt+(" ). For example, configure it to launch "gedit".
3. Press Shift+Alt+9

Expected result: gedit opens

Actual result: Nothing happens. The keyboard input passes through to applications, as can be seen if you run cat in a terminal and press Shift+Alt+9 -- ^[( appears in the terminal.

Shift+Alt+0 (which can also be thought of as "Shift+Alt+)" ) is broken in the same way. Binding to other key shortcuts works as expected.
