Public bug reported: Steps to reproduce:
1. Have 14.04 and unity/compiz installed. 2. Configure the system to log in automatically. 3. Plug in a Logitech C920 webcam. 4. Cause some program to generate a crash dump with "kill -11" 5. Restart the computer. Result: Upon booting, the system automatically logs in and then crashes within 1 second. It happens so fast that it's difficult to tell what happens, and you get dumped back at the login screen. Deleting the pending crash report from /var/crash causes everything to work again, until some other program crashes. Removing the webcam from the system or replacing it with a different webcam prevents the crash. Logging in manually prevents the crash too. A retraced crash file with backtrace is attached.
