Title:
  idle-python2.7 - blank window (after ubutu upgrade to 13.10)

Status in “python3.1” package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  after upgrade of Ubuntu from 13.04 to 13.10, Idle for Python 2.7 has not been working any more:
  1) When I choose to open an existing module, I get a blank window (as if the file was empty).
  2) I cannot close the window. (No response to clicking on the button.)

  When run in the terminal, I get:

  problem 1:
  ==========

  Idle-python3.3 works fine.
