Yep, although it didn't happen as soon as I installed iOS 9.0b1. It was fine, but just recently it's started every time, including b2. In order to install the full download (didn't wait for the OTA as I wanted a clean install) I had to erase all content and settings before iTunes let me click the icon and choose the restore. I tried all the usual things like different user accounts and safe modes / new libraries etc, to no avail. Up to date version of iTunes, the only possible thing being the fact it's a beta iOS and a beta OS X (El Capitan).
Once I got my initial install and sync of all my apps, it's gone back to the same issue of crashing iTunes.
