+Summary: NullReferenceException in ErrorProvider.SetError
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+NullReference exception when calling SetError on ErrorProvider.
+
+Steps to reproduce the problem:
+1. Create A form with an ErrorProvider and a button
+2. In onclick of the button do errorProvider.SetError( button1, "Error" );
+
+Actual Results:
+NullReferenceException
+
+Expected Results:
+Error message with button
+
+How often does this happen? 
+Allways
+
+Additional Information:
+In the GetErrorProperty the check for a null value is after casting it. So
+if there is no errorproperty yet it will always throw a NullReferenceException.
