From Josh Ritter:

A number of our Windows customers have an issue with the sqlite3
module included with Python 2.5.1

We've tracked the problem down to the sqlite3.dll included with the
Python 2.5.1 distribition.  It is stripped and thus cannot be relocated.
This causes the following exception on computers where something is
already loaded into the address the sqlite3.dll wants to use:

File "sqlite3\__init__.pyc", line 24, in <module>
File "sqlite3\dbapi2.pyc", line 27, in <module>
ImportError: DLL load failed: Invalid access to memory location.

I downloaded the latest sqlite3.dll from http://www.sqlite.org and
this fixes the problem.  (This dll isn't stripped)
