title: Android Wear app crashing with FATAL EXCEPTION: IntentService[CalendarQueryService]
body: <p>I've been looking for others suffering the same issue but can't seem to find any posts.</p>
  
  <p>Anyway, I've been using the LG G watch with my Nexus 5 but after a few days, the Android Wear app crashes continuously i.e. I keep getting 'Android Wear has stopped unexpectedly' dialogs over and over again. It gets to the point where I have to uninstall the Wear app, thus making wearing the G watch pretty pointless! Reinstalling the app straight away results in the same. I reinstalled the app after a few days (and saw an update had been pushed) and it was fine but a couple of days later: the same thing happened.</p>
  
  <p>The logcat output shows:</p>

  <p>Being the actual Android Wear app, I'm not sure what I can do to fix the issue. Any suggestions please?</p>
  
  <p>Thanks.</p>
