I have seen similar errors myself and am unable to reliably reproduce
them.  Workaround: run only the output pass, e.g.

  cvs2hg [...other args...] --pass 16

So far, that has worked for me every time.  No idea why.  Updating
README.cvs2hg now...

Unrelated.  That just means you're running cvs2hg with a different
version of Python than was used to build Mercurial.  That's a bit
dodgy, but there are definitely worse things you can do on a computer.
