ISight broken after 2010-005 OS X 10.6.4 security update

Question

I've looked around everywhere for a solution, but absolutely nothing I've tried so far has worked, so I think this might be an issue with the new security update. After installing security update 2010-005 on my MacBook Pro with OS X 10.6.4, iSight no longer functions with third-party applications. Skype crashes immediately upon attempting load my video during a video call or opening the video preference pane, and ManyCam quits as soon as it opens. I also updated my other MacBook with OS X 10.5.8, but it has had no issues with iSight and third-party applications.

Welcome to Discussions, dr trrbl
I am using the latest software, including SU 2010-005 on my MBP. Its iSight works fine with my Apple apps. (I don't use any third-party software that can use webcams, so I cannot test that.)
(1) If you have not used Disk Utility to repair permissions since you installed the update, restart Mac and repair permissions now. Then test your iSight again. If your problem remains, try the normal iSight troubleshooting process:
(2) For any iSight problems, first try restarting the Mac. If the problems persist, try all relevant suggestions from:
  http://support.apple.com/kb/HT2090
You can use QuickTime X and iMovie to test whether your iSight works with Apple apps. Test with only one app open at a time; i.e., test each app one-at-a-time before you try ManyCam.
If your iSight problem still occurs in more than one app and more than one user account, the reset suggested in the Troubleshooting app often restores proper function of inbuilt iSight.
However, if your built-in iSight still does not work after carefully following all the suggestions in the "How to Troubleshoot iSight" article, and if iSight does not show as a USB hardware device in your Mac's System Profiler utility, yours is most likely a hardware problem. In that case, contact Apple or an Apple-Authorized Service Provider for service.
(3) If your iSight is recognized in System Profiler but does not work with any app in any user account you test, you may have had a bad download or install of SU2010-005. Try reinstalling as follows:
 • Restart Mac.
 • Repair permissions.
 • Download and install Security Update 2010-005 (Snow Leopard - Client)
    http://support.apple.com/downloads/DL1094/en_US/SecUpd2010-005Snow.dmg
 • After the restart that completes the install, repair permissions again.
Then test iSight one more time using the Troubleshooting method. It should work.
(4) If you only have trouble with third-party apps, check their web sites for possible known-issues or later compatibility version updates.
We will watch for your status update.
