title: Error Message after closing Qt creator 5 : "Unexpected CDB error"
body: <p>Even after just creating a simple new project, sometimes after exiting qt creator it closes with the message <strong>"Unexpected CDB Error "</strong>. As it's related to debugger, I have tried with fresh installation of debugger many times, it still closes with the same error.</p>
  
  <p>Any one having any idea about this? </p>
