I talked with seb128 and wants to re-evaluate the way of shortcuts handling, so this is a transitional solution in trusty. We have a chance to get rid of ibus integration from GNOME in trusty to avoid such odd situation.
Also <Super>Space isn't really good UX, and might be reverted later. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ibus in Ubuntu. https://bugs.launchpad.net/bugs/1249208 Title: Avoid conflicting <Super>Space shortcut with g-s-d Status in “ibus” package in Ubuntu: Fix Released Status in “ibus” source package in Saucy: Confirmed Bug description: [Impact] Now we are using <Super>Space as the shortcut of switching IME forward, and the shortcut is handled twice: first in g-s-d and then in ibus. This leads to a conflict and the shortcut does not really work. [Test Case] Old behavior: Press <Super>Space does not have any effect of changing the IME forward. Expected behavior: After installing the updated package, user removes ibus configuration files in ~/.config/ibus and ~/.cache/ibus, and re-login to the system, <Super>Space should work for people who are using Unity or GNOME Shell. [Regression Potential] IBus may still push notification message about <Super>Space as the shortcut for users of other desktop, but the shortcut in effect would be <Ctrl>Space when there is no other program grabbing the key press (like what g-s-d does).
