[Twisted-Python] Errors after upgrading to 2.0.1

[snacktime]

I'm testing out an application I wrote in 1.3.  In 2.0.1 I get a
warning and an exception.

The UserWarning about SSL I looked up on the list and I understand why
it's there, although I think it's a bad idea.  The warning is about a
bug in pyopenssl that hasn't been fixed in pyopenssl.  In addition
there is no reason to think it will ever be fixed after being ignored
for this long.  Maybe someone could find a better solution for this
warning other then leaving it to end user to find the patch on the
mailing list, which for all I know might not even work at this point. 
 Maybe put up a patched copy of pyopenssl on twistedmatrix.com?  Seems
better than having an unmaintained dependancy in twisted.

The exception I really have no clue about, maybe someone could point
out where the problem is?
