Find and remove a system-wide keyboard shortcut

After updating to Xubuntu 14.04 the other day, I noticed Ctrl + Space stopped working in both Eclipse and NetBeans, but I cannot find where it's bound. Nor does it appear to do anything.

I have looked in the Settings Manager on the Keyboard, Window Manager, and Settings Editor (XFCE-specific) applets, but none of the commands are bound to that combination. Is there another applet that defines system-wide shortcuts?

According to this bug thread, one of the recent versions of ibus was either added in 14.04 or added a new key binding for switching input methods. Luckily, removing the binding is trivial.

1. Run ibus-setup from the command line
2. Click ... to the far right of Next input method
3. Click Delete
4. Click OK
5. Click Close

Note to future self: Never dismiss the most obvious search query—"ubuntu 14.04 ctrl-space"—without trying it first!
