2to3 takes the conservative route of assuming your application treats dict.items() as a list in all cases; this is not nessicarily true (of course), but it is safe, and interestingly, backwards compatible.

-                    raise exc_info[0], exc_info[1], exc_info[2]
+                    raise exc_info[0](exc_info[1]).with_traceback(exc_info[2])

The exception raising syntax has changed; you can not re-raise an exception using tuple notation any more. The new syntax is far clearer, but I'm unsure of back-compatibility or even if it is possible to emulate it completely as a polygot (2.x and 3.x w/ same code).
