Yes, the fix is in the Telerik Testing Framework.

Pavel, 
Does the latest Telerik Testing Framework contain a fix too?

The application is crashing on the Close Window step. That step is marked Passed by Test Studio. That crashed application causes the next test step to fail. This is the stack trace reported:

System.NullReferenceException was unhandled
  HResult=-2147467261
  Message=Object reference not set to an instance of an object.
