Oh, sorry, it's d1d251292ee7. (I got the short rev from the hg.python.org interface, so I thought it would be "authoritative" enough, but I guess it is ambiguous)

When I do "import shutil" inside _backport/shutil.py, it seems to be importing itself (??) if I don't explicitly enable absolute imports (in python 2.7). If I delete the "class Error" definition and instead add "from shutil import Error", I get an ImportError.
