PlacePicker.IntentBuilder se cierra inmediatamente después de abrir

Implementé la interfaz de usuario de PlacePicker.IntentBuilder en mi aplicación. Para el más largo que trabajó con ningún problema, pero ahora tan pronto como la interfaz de usuario aparece, se cierra y no estoy seguro de por qué. La cosa loca está mirando el logcat que no se estrella ni causa ninguna excepción así que no sé cuál es el problema. Esta es la clase que crea y lo llama.
