NullReferenceException from TrackCurrentCultureBehavior when changing culture #23

Closed donwilliam closed 6 years ago

donwilliam commented 6 years ago

Changing culture resulted in the following exception. The TrackCurrentCultureBehavior might be used wrongly, but a crash is unacceptable here.

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object.
