Sorry for posting here, however, I can't sign in to bitbucket, I get a 403 error.
So I'm posting this bug report here, with the suggested fix:
In the Lua interval module.
I think this:
else if(!strcmp(key, "running")) lua_pushinteger(L, is_intervalometer_running());
should be
else if(!strcmp(key, "running")) lua_pushboolean(L, is_intervalometer_running());
