Are you really running with mpsw.py?
For me, the C (=cpyext based) version of apsw works (slowly),
but mpsw gives me:
>From callback <function xOpen at 0x0000000005575ad8>:
Traceback (most recent call last):
File "/home/amauryfa/python/madis/apsw.py", line 924, in xOpen
self._vtcursorcolumn.append(instance.Column)
AttributeError: Cursor instance has no attribute 'Column'
