Plugin Stops loading if sonos device missing

I'm on the latest version (0.8.33), and got the following in my event log after one of my sonos speakers became unplugged. Looks like it isn't handling a device not found gracefully. Obviously not a big deal, and I was able to fix things by plugging the speaker back in or disabling the device in indigo.

Here's the log:
