Can't help on the specific problem, but two points:

1. You are supposed to be returning \r\n, I believe, not just
\n between lines.

2. If you want to see what is going wrong, put a try/except
around the import statement and try to write something useful
along with your results:

err = ''
try:
    import logging
except Exception, ex:
    err = str(ex)

print 'Content-type: test/html\r\n\r\n'
blah blah blah
print '<p>Error: %s</p>\r\n'

If you can manage to import the sys and traceback modules,
you can get a more fully formatted exception using
''.join(traceback.format_exception(*sys.exc_info()))
