I don't know about your problem specifically, but would you post the output
from.
cat /proc/asound/cards

First do this booting up with the webcam unplugged, then shutdown, plugin the
webcam, reboot, and run cat /proc/asound/cards again.

It will be interesting to see if, when the webcam is plugged in, it is being
detected as card0. ( that is, the usb mike part of it), and your sound card
is being set as card1.

I added the above info to the bugzilla, but there is no card1, the nvidia
sound just completely disappears.

Can you also post the output of /sbin/lsusb with the webcam plugged in, and
also the output from /sbin/lsmod.

I think all the other info is already buried in some of the log files
I added to the bugzilla.

However, the most interesting fact so far is that if I rename the
snd-usb-audio.ko kernel module so it can't be loaded, I can boot with
the webcam plugged in, and everything (except, of course, the USB
microphone) works fine.
