[MonoDevelop] on the fly code formatting issue with readonly properties

[Sergey Lobko-Lobanovsky]

I am using the on the fly code formatting option and I keep getting this
error when I have readonly properties in an interface defition, such as

public interface ISearchable
{
string Content { get; }
}

Is this a known issue? Exception stack trace below:

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
