Ah.  I missed the change.  Did that ... and it did help but then it does
the same thing somewhere else:

Thanks very much for the Linux pointers.  I'll try those.

At some point, I'll need to speak to the prospects for making this work on
Windows.  Can you point me to a ticket for the "OpenCV’s algorithm factory
code on Windows" issue you mentioned or otherwise comment on the prospects
for a fix?

msr
