I just installed it to lock display with long pressure of proximity sensor, but I can't use any function of proximity sensor!
I checked it with healtcheck, and I'm sure sensor works, but seems shortcutd can't recognize it.
I have last version of proximityd package.

Here is a strace of shortcutd (killed and then restarted with strace)

There are some "Resource temporarily unavailable", may be this a problem?
