I have the same problem. I have noticed it using Skype 4.3.0.37 on
Ubuntu 14.04 using the official kernel 3.13.0-37-generic. If I do not
activate my cam everything is working fine but as soon as I switch on my
cam the audio start to be unstable and the video freeze.

In my case it does not affect cheese.

Title:
  webcam freezes after 10-30 seconds

Status in “cheese” package in Ubuntu:
  Confirmed
Status in “skype” package in Ubuntu:
  New

Bug description:
  
  This is probably a kernel module or low level library problem (gsteamer?) Same issue happens with other webcam applications including:
  Skype (4.1.20)
  Google Gtalk browser plugin.

  I would be happy to point this to right direction.

  Further error output from cheese:
