+Summary: PropertyGrid does not correctly change SelectedObject - it crashs
+
+Description of Problem:
+When you set property SelectedObject of PropertyGrid to object with 
+properties, then to some object without properties and after that to 
+object with properties, it will crash
+
+Steps to reproduce the problem:
+1. Create application with PropertyGrid and two buttons (button1, button2)
+2. Create class without any property (I will use the name TestCleanClass 
+for it)
+3. OnLoad of Form with property grid call this:
+this.propertyGrid1.SelectedObject = button1;
+this.propertyGrid1.SelectedObject = new TestCleanClass();
+this.propertyGrid1.SelectedObject = button2;
+
+Actual Results:
+The application crashs
+
+Expected Results:
+The property grid will show properties of button2
