Grabbed the deb from the jenkins run and installed it on my bq e4.5. I paired my selfie button and when I press the Android (enter key) button, nothing happens. When I press the iOS button (vol+) I get the volume overlay appear. Like this:-

No photos are taken.

@Ugo: Submitted against wrong branch.
@Alan: camera is distributed as a click app so installing the deb while the original click is installed would cause the click to be run instead of the deb version.

There were changes to keyboard handling in staging in the meantime, please make sure it merges with no breakages.
