Yes, I've noticed this yesterday, seems to be some incompatible release of the crontab python package. In master (d7d51b493fc2462df6de3fd40adf59b1bf88361d), I've made yacron pin the version of crontab to an older known to be working version 0.22.6.

If you install yacron like this, it should work:

pip install crontab==0.22.6 yacron

I released version 0.10.1 with the install requirement fix.
