Code review comment for lp:~mniess/ubuntu/trusty/ibus/fix-lp1240198

@Bruno sorry I didn't get to it, yet. As utopic is released the whole thing needs to be based on vivid (15.04) now, right? My time-consuming day job prevented me from installing anything but trusty on my machines until now.

So the only thing really is changing the default for "use-system-keyboard-layout" back to the old default (true).

I would love to work on this but I cannot promise I'll find the time to install vivid soon, to test it there.
