For 32-bit Karmic Koala, I found this thread & solution. I have included the preload for the /usr/lib and the /usr/lib32. For me the former works and I assume the latter works for 64 bit (as skype runs in 32 bit).
1. sudo mv the /usr/bin/skype binary to /usr/bin/skype.real
2. sudo gedit /usr/bin/skype
(or your favorite text editor instead of gedit)
3. copy & past into the editor the following
#!/bin/bash
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype.real
4. enter "sudo chmod 755 /usr/bin/skype" without quotes to make the script file executable
5. start skype via the menu and test the video
