error run_tests.py

Dear Experts,

My nickname is pyontaku14. I tried run_tests.py with Python2.7.8 on Windows8.1.

The result of "python run_tests.py --filter-less" is the attached 150621_sfepy_test_filter.txt. The result of "python run_tests.py --debug" is the attached 150621_sfepy_test_debug.txt. "AttributeError: SetSource" is in 50621_sfepy_test_debug.txt. I could not understand what this error is.

I guess all required modules are installed. Could you please tell me what to do? Any help is welcome.

Best regards,
