[Jaunty]installing with "free software only" and backports enables unfree backports

Binary package hint: debian-installer

I installed with the Jaunty Jackalope Alpha 2 i386 alternate CD and selected "Free Software only", and "Expert Mode". I was then asked, if I wanted to include backported software, I opted for yes.
When I investigated my sources.lst file, I noted, that from the backport-repository, not only 'main universe', but actually 'main restricted universe multiverse' was enabled. If now somebody backports some newer version of some nonfree software, I could install it via synaptic or apt-get, not nowing it to be unfree.

The sources.lst file should only reference 'main universe' as sources if I choose 'Free Software only', also with backported software. Similar problems with the CD and -security as a source are described and fixed in #220805, I guess the same fixes described there could just be used to fix -backports.

Thanks,

Mika
