Comment 2 for bug 367287

I'm sorry for the trouble, thanks for assigning it correctly know.
Though I have to admit I still don't know why that is, seeing that I can "apt-get install kubuntu-restricted-extras" and it does something different than "apt-get install ubuntu-restricted-extras" would do, and I never installed or even looked at the source packets (that are the one added with "deb-src" in sources.list, right?).
