(Get the code!)
This affects me, too. I installed Ubuntu Desktop 10.04 (amd64) Final. This problem was present at the first boot. No updates have fixed or affected the problem. I have not tried any further troubleshooting steps (such as blacklisting gspca_vc032x, above).
When the warning dialog occurs, hitting Cancel will leave GDM unresponsive indefinitely (it just says "Canceling..." and the user/password area remains frozen). Hitting Logout leaves the system with extremely poor disk performance. It literally crawls.
If this performance issue also affects the live CD, it may explain why my live CD and CD installation boot speeds (even just to do the media check) were unusually slow (e.g. minutes instead of seconds).
Waiting a while at the GDM login screen seems to prevent the "power manager is still running" warning from popping up. It seems like the power manager service is hanging (i.e. timing out) on some device, so I'm attaching my lspci -v and lsusb -v device lists.
