Python 3 doesn't work

[kentonv]

1. Create a new grain.
2. Create a new notebook with Python 3.
3. Wait for the kernel to start.

After a while, an error appears:

The kernel appears to have died. It will restart automatically.

Then another error appears:

The kernel has died, and the automatic restart has failed. It is possible the kernel cannot be restarted. If you are not able to restart the kernel, you will still be able to save the notebook, but running code will no longer work until the notebook is reopened.

It appears Python 3 doesn't work at all.

Python 2 seems to work fine.
