I was using epydoc and docutils 0.5 to build my documentation. Epydoc
crashed with this error. If you google "AccessInit: hash collision: 3
for both 1 and 1", you'll see it's not just me. After I applied my
patch, things seem to work fine.
Seems to be a problem with Django and Sphinx and Satchmo, too. And
it looks like maybe it only occurs on Windows. I ran into it using
PIL built with msys for Python 2.6.4 on Windows XP. I've never seen
it on OS X or Ubuntu or Fedora.
By the way, "exit(1)" is pretty harsh. Shouldn't you somehow throw a
Python exception there? Give us a better chance of figuring out where
it's being called from.
