"TypeError: read-only buffer, None" returned from file.write...

[Adam Ruth]

I get this all the time too, simple error.  Somewhere you assigned sBuffer
to None.  It happens to me a lot when I call functions that return strings
or return None when there is a problem.  You can confirm this by writing:

f.write(str(sBuffer))

The file then should contain the word 'None'.
