Update
I think I fixed or at least solved the problem.
It has nothing to do with the screensaver. I realized this when it I installed it on my win 7 partition. The issue lies in the sources.xml file
I removed all of the custom entries so its blank and now I haven't had any issues. (For at least 3 days) I don't really understand where the "special//music" folder is and was.
Maybe the issue was the program was trying to sync across to another HD?
Not sure, the log is still relevant. I haven't heard anything yet from Boxee, but here is an update for y'all.
