@tasos: Your code looks correct. Can you try renaming the folder from "slymlyne sidebar" to "slymlyne_sidebar" (basically use _ instead of space). And do the same inside the XML for the value of skin_name. I want to make sure that the space is not causing the problem.
If that doesn't work again, I have another idea. I see that this skin's parent is "slymlyne". Maybe you haven't applied the XML fix to the parent skin and it's possible that this is causing a black screen.
