something stealing Ctrl-Space

[Miles Bader]

As of today, the Control-Space key combination is no longer being
passed through to any apps, in particular, gnome-terminal and Emacs.
As this is a very important Emacs key-combination, this makes using
Emacs difficult...

I'm not sure at all where to look for the problem, but I notice
gnome-shell got updated yesterday, and it would certainly be in a
position to steal keys.

I also use "mozc" for Japanese input, which I notice is no longer
working....  This may be relevant, because I think the default enable
key for mozc is Ctrl-Space, but I had changed it to Shift-Space
instead.  I cannot verify this that my change is still active,
however, as the "settings" command in the mozc menu [in the little
icon in the screen title bar] now does nothing... ><

Anybody have any idea what's up?

Thanks,

-miles
