Comment (by joncampbell):

 @costdev
 I totally get it now.
 The person who developed the widget that stopped working in 5.9 had an
 update() method that was empty and returned nothing.

 I removed that from the custom widget class and now when the widget saves
 it stores an empty array so that the widget loading on the front end has
 an empty array of settings instead of null.

 Feel free to get rid of this fix if the only way people would have a null
 settings is if they did it wrong.
