Pope Benedict had planned to visit Sapienza University of Rome, perhaps Italy's most prestigious university, to celebrate the start of the academic year. Instead, a coalition of students and professors demanded he stay away, so he did. Their complaint is that the Pope, an advocate of free inquiry and the importance of reason, is responsible for Galileo or something like that.
This has lead recriminations from Italy's left wing government, with both the president and Prime Minister condemning the actions of the protesters.
The Vatican has released the text of the Pope's undelivered speech. Unfortunately, I have not been able to find it in either English or Italian. I probably will have more to say once I read it.
