[Development] Qt/XCB applications and deadkeys and ibus (which cease working) (and sometimes the entire keyboard in Konsole)

That's not what I saw. Ibus was always launched at login, and im-config seems to 
get some length to ensure that applications always use the "best" method 
available if the user didn't configure things to use a specific method. That's why 
newly launched Qt applications work fine after exiting ibus. The loss of keyboard 
input in Qt5 applications is a priori not a packaging fault but a regression in 
Qt itself.

Thanks for the suggestion, at least I could uninstall that one without taking a 
sh*load of other packages along with it...
What env. variable would that be (I don't want to log off and on AGAIN just yet 
:))
