So, do you have this file?

Yeah, probably true.  Still worth a look though.

Yep, you're clearly getting a hang there.  Have you tried this with
another machine that wouldn't be a mirror image of the one you're
using?  Could be a machine specific configuration thing.  If it doesn't
work for you from more than 1 machine and it's not an external source
like BLODA and it's not something on the server side, then it looks
like you're stuck trying to debug this in the source.
