Here is the problem:                                          ^^^^^^^^^^^^
You are calling the unicode function with three arguments ;-).
Unfortunately, by default you do not get a traceback that points out the problem.

You can enable the tracebacks with these lines at  the top of your script:

import logging
logging.basicConfig(level=logging.WARNING)

BTW:  I see that you are using an old version of comtypes (in recent versions the CreateObject function
does not accept a 'sink' argument any longer; you have to setup the events by calling
comtypes.client.GetEvents function, and keep the returned object as long as you want
to receive the events).  Unfortunately I have never released a newer comtypes, but
you can get it with 'easy_install comtypes==dev', if you have svn installed.

PS: I'll attach a working script that I have made, it connects to internet explorer which
is my favorite com client for testing (although I don't use it for browsing).
