REVISION SUMMARY
  As a temporary workaround for the problems with nested eventloops
  and warning messages in the move/copy operation when it can't
  change the destination file rights and the user is asked to retry
  and after some failed retries he press cancel.
  Even this is not the right solution, this fixes the crash of:
  BUG: 364039
  The right solution implies also solving:
  BUG: 332948
