AttributeError when running tests

I am gettig an AttributeError when running glue -t

Traceback (most recent call last):
  File "...../bin/glue", line 11, in <module>
    sys.exit(main())
  File "...../lib/python3.4/site-packages/glue/main.py", line 224, in main
    return run_tests()
  File "...../lib/python3.4/site-packages/glue/main.py", line 138, in run_tests
    test.main()
AttributeError: 'function' object has no attribute 'main'

I think there is some kind of name conflict: renaming the test.py module to anything else makes the tests start fine.
