Some test fails on 0.29.0 (win32)

Look at test output below.
Is this a test issue ? (Or, why "Expected output tree so strange?")

--- test output ---
c:\svn\tests\clients\cmdline>python commit_tests.py 22
Got singleton from actual tree: C:
 * Node name: C:
    Path: __SVN_ROOT_NODE/C:
    Contents: None

    Children: 1
Output of commit is unexpected.
