I'm willing to believe that this fixes the problem, but I don't see how this
works, and in the interests of bettering my Python understanding, could
someone explain it?

sys is imported at the top of storage.py, so I see that the "import sys" is
no longer necessary.  What I don't get is how there could be this error:

"""
File "/Users/chris/Desktop/spambayes-1.0a5/spambayes/storage.py", line 652,
in open_storage

    print >> sys.stderr, """\

UnboundLocalError: local variable 'sys' referenced before Assignment
"""

when sys has been imported.  Especially since the change is removing a line
*after* the crash.  What am I missing?
