I just ran into the same thing today not an hour ago. No idea what triggered 
it, but I haven't seen it before. I solved it by starting ibus, but I guess 
that just adds another layer of interpretting keys. Also newly started qt5 
applications had working dead-keys too, it was just all running qt5 
applications that broke.
