Compose key doesn't use default compose mapping

Hi! I’ve been using the compose key for a while, but recently the default mappings stopped working (only the mappings in my ~/.XCompose still work). Both /usr/share/X11/locale/compose.dir and /usr/share/X11/locale/en_US.UTF-8/Compose exist, but it doesn’t seem to be using them. Any dieas?
