Same outcome on 1.3-branch.

mcdonc added a commit that referenced this issue Jul 13, 2012
@mcdonc
- On at least one 64-bit Ubuntu system under Python 3.2, using the
e652518 
  ``view_config`` decorator caused a ``RuntimeError: dictionary changed size
  during iteration`` exception.  It no longer does.  See
  #635 for more information.

- Fixes issue #635.
