iTunes quits unexpectedly with iPhone 4s after Lion upgrade

Just upgraded to Lion on my iMac. iTunes and my iPhone 4S are all updated to current versions. When iPhone is connected to iMac and iTunes is open, iTune quits when I select the iPhone device listing after about 3-4 seconds. It quits only when i select the device name not if I select any of the content items (Music, Movies, etc) under the device name.
