IDLE is behaving badly in Python 2.7.6rc1 with a fresh install.

The problem occurs with a sequence of creating a new window, pasting code, and running the code:   Cmd-N, Cmd-V, Cmd-S, F5

The visible effect in IDLE is that a new window named "idle" is created and is unresponsive.  Behind the scenes, the following tracebacks occur.

-----------------------------------------

This is a duplicate of Issue19426.  The fix for it will be in 2.7.6 final.

P.S. For users comfortable with the command line, there is an procedure documented here for applying the fix to 2.7.6rc1 (2.7.6 final is expected soon):  http://bugs.python.org/issue19484#msg202062
