For me, the behaviour is completely the opposite of those reported by others:
Apps with Compose key working: - Gnome Terminal, Dash search field
Apps with Compose key ineffective - Gedit, LibreOffice, Chrome, Firefox
But when creating a new user and copying my .XCompose to him, for that user the Compose key works in all applications.
