Python2.7 segfaults on i2c write
I did a simple hardware twitter client using Omega2+ Arduino Dock2 and LCD Keypad Shield.
I use i2c to send tweets to arduino sketch. And sometimes python just segfaults.
First time it happened on "How dangerous is Putin?" tweet. https://www.instagram.com/p/BP6Z0SVhoyC
But this is not a RussianHackers(tm) work, I checked!
And i have latest versions of everything
Ω-ware: 0.1.9 b149
python - 2.7.13-3
pyOmegaExpansion - 0.4-1
That's what I see in logs:

P.S.: I have just found out that I can actually use Py3 with OmegaExpansion module, so I am going to try if it works better, but if the problem is in c moule it won't help :(
@Sergey-Melekhin looks like there is no esay way to run OmegaExpansion in py3k :(
People why do you even start writing new python2.7 libs in 2016? Only time since 2006 when I used py2 for a new project was when I needed scrapy, which was too big to port easily.
