I noticed that you cannot set/calulate a duration for the google slide show widget when using it in a playlist. This causes the widget to get stuck on an infinite loop and not continue to the next item in the playlist.

There is also the issue that when using just the widget, it will fail into a imortal "Loading Widget" screen and force us to restart the entire app. I found an easier fix by creating two identical layouts and just switching between the two each time it happens. 

This issue happens about once a day, usually in the mornings.
