You convinced me that I should be fine using guile from testing.

I've added the following lines in sources.list:

deb http://ftp.ch.debian.org/debian/ testing main
deb-src http://ftp.ch.debian.org/debian/ testing main

created /etc/apt/preferences.d/00-stable containing:

Package: *
Pin: release a=stable
Pin-Priority: 800

and created /etc/apt/preferences.d/20-guile containing:

Package: guile
Pin: release a=testing
Pin-Priority: 600

Now, before installing guile from testing, I wanted to check if I still
get no updatable packages as a moment before doing the change:

aptitude update
aptitude full-upgrade

This tells me that the package libxnvctrl0 can be update. If I remove
the testing entry from sources.list, then I get no updates. So, something
is coming in from testing.

Am I doing something wrong?
