Failed test_chinese_user_agent/test_russian_cp1251_user_agent with Python 2.7.10

[felixonmars]

I am getting the test failures with Python 2.7.10, while with Python 3.4.3 it works fine. I have tried to set LC_ALL to en_US.UTF-8 but it doesn't help. Any hints?

More package versions:
flask-login 0.3.0
flask 0.10.1
werkzeug 0.10.4
blinker 1.4
nose 1.3.7

Seems like a bug in Python 2.7.10; all tests pass in 2.7.9.

[dev-zero]

reproduced with python 2.7.11

Python 2.x is EOL; closing.
