Having read your post I've found that my (working prefectly as far as I'm aware) shows exactly the same error:

Jan 5 13:09:01 tvbox mythpreviewgen: mythpreviewgen[32451]: E CoreContext main.cpp:81 (preview_helper) Setting priority failed.#012#011#011#011eno: Permission denied (13)

Adding some context around the error line tends to suggest though that it's perhaps not anything to worry about:
