Unfortunately, I don't know where the problem originates. Either the SQLite 3.3.4 DLL that was originally imported into Python was stripped and current ones aren't. Or somewhere in the Python win32 build process DLLs are stripped.

Maybe we should just update the SQLite3.DLL to a current one in the Python 2.5 branch. Due to their extensive regression tests new ones should generally be better than old ones. And the current SQLite DLL is too old for some cases (SQLAlchemy refuses to work with it because it's too old and buggy, for example).
