Works on my machine. Going to try installing on Linux and see if I can repro there.

Sorry forgot to mention am on CentOS Linux release 7.1.1503 (Core) Let me know if you need any more info.

We've traced this issue to a bug in the Python interpreter, specifically in PyUnicode_FromFormat.

It's probably this, fixed in 2.7.9: https://bugs.python.org/issue22023 - notably the system Python in Ubuntu 14.04 is 2.7.6, so v8py won't work there currently.

Thanks for v8py, it seems very well put-together.

Thanks for tracking that down alex!
