In the case where you have a content app configured to have thumbnail view, if you have 2 or less items then switching to thumbnail view throws divide by zero exception.

To reproduce:

Delete contacts from the contacts apps so that you have only 2 (Note: 3 or more contacts works ok)
Try and switch to thumbnail view
Observe the below error
