Cannot access a disposed object from MdiControlStrip.GetTargetWindowIcon()

I generally understand exception Cannot access a disposed object. But this time it seems to be originating in non-user code. It occurrs occassionally when a form is closed. It looks like some automatic UI refresh is ongoing:

Message: Cannot access a disposed object.

It is possible this one is thrown only debugger session, I haven't seen it in production so far. (See the bottommost item of the stack trace.)

  Is my assumption (that this is caused only by debugging session) correct? Or should I worry about the same problem in production?

  Can this problem be somehow avoided?
