Steps to Reproduce (unexpected behavior in bold):
- I successfully create an app contact via the Python Starter App
- I successfully subscribe to timeline notifications
- I take a photo with Glass
- I share that photo with my app contact
- The photo is duplicated on the timeline
- The app's callbackUrl is never pinged (yet POSTing manually via curl works fine)
- Attempting to delete the duplicated photo card makes the Glass OS glitch out until reboot
