I'm also having trouble with getting the global shortcuts to work. Ctrl-Shift-X, P works fine. But Ctrl-Shift-H or the other predefined key combos do not work.

Tried running keyboard-shortcut from xterm and it gives me this:

Traceback (most recent call last):
File "/usr/bin/keyboard-shortcut", line 31, in <module>
kn = int(sys.argv[5])
IndexError: list index out of range

I don't know if this helps.

Otherwise, shortcuts within dashboard/launcher are working as advertised. Thanks.
