No, it does not happen usually. In fact it should never happen for stock mediaplayer. If you look at original Nokia cgroup configuration you will see there is a "Multimedia"(or something like that) group. Your "patch" throws that setup through the window.

And I really will appreciate if you describe (not in short) what your "patch" is doing. I don't want to be offensive but my six sense is telling me that your "patch" is solving problems introduced by it.

So, will you please describe what exactly it does(without redirecting to what Linus or someone else have said). In such a way that everyone with some technical background to be able to understand. Thanks.
