Ubuntu 14.04 beta, upgraded April 12, 2014 from Ubuntu 13.10
I have two input sources - English and Russian. I've set up "Caps Lock" key at Systems Settings->Text Entry->Switch to next source using. Now if I am pressing Caps Lock the source indicator quickly changes state as En->Ru->En->Ru->En (or Ru->En->Ru), so actually input source never changes. Using other keys (or combinations) to change input source works as intended, changes En to Ru and vice versa.
