robot_remocon crashes when pairing master not fully ready #23

There is some delay between the paring master (public) is available (robot_remocon finds it) and it being fully configured/ready. I currently believe this is the time interval when the pushing and pulling is going on. If the robot_remocon connects during that time it crashes 100% of the time.

Ah, good point. I need a wait for service of some sort. On Jul 3, 2013 9:44 AM, "Marcus Liebhardt" notifications@github.com wrote:

It wasn't checking to see if it had actually found the app manager namespace (via master system state lookups), and thus crashed when the namespace was still null.
