AFAIK, the only recent Python issue related to GNU readline was 
Issue20374 but it seems you've already eliminated that.  The current 
assumption is that Python 2.7.6+, 3.3.5, and 3.4.0 have no problems with 
readline 6.3.  If you end up believing that there is a Python problem 
with it, please open an issue on the Python bug tracker.  Thanks!
