This is were I stop last time I worked with pygit2 on Windows.

The bug can be fixed either in libgit2 or in pygit2. Check libgit2/libgit2#462

To me it is better to fix it in libgit2, but I will accept a (temporary) solution just for pygit2.

@jdavid
I can be sure now, that
ERROR: test_read_tree (test.test_index.IndexTest)
is because the problem pygit2. there is circular references betweeen Repository and Index.
so remove the reference, the problem is resolved. Please check it carefully!. You reject it before.

ERROR: test_new_tag (test.test_tag.TagTest)

The cause of test_new_tag still unknow.
