I have done some research on this file and yes - it is related to Youtube and is a permission for storage of certian profile files and the like that is asked of you when you upload files from your camera to youtube or visit a site which has youtube clips embedded in it - which WGT has lots.
N.B. it is not a spy file!!! Youtube clearly asks you permission and states what it's for!!
See below link for a concise explanation and help to combat it -

This quote from Jonny at this forum - "The Flash Camera Access prompt is well worded, conceise, and makes no attempt to access your camera in the background. Its called a Prompt because, it does just that, it Prompts you, asking you if you mind if we can have access your camera. NOTE - Accessing Camera, and HAVING access to the camera are 2 completely different things."
Hope this helps
