Nanpy on Leonardo doesn't work - Reported by Fernando Molina

[astagi]

Ok, It's not a big deal, I don't know why (could be archlinux is tricking me) it seems to connect to arduino, no errors, but when arrives here:
Arduino.pinMode(13, Arduino.OUTPUT)

It seems to freeze (blink example) in the arduino the led do nothing It just bright (no blinking). Tried with python 2.7 and python 3.3 they both seems to freeze in the same line.
Could it be autoreset?

Board = leonardo
Python 3.3 and 2.7
S.O. Archlinux

Let me know if you need something more
