An experiment:
Code:
debian64:~$ cat /etc/apt/apt.conf
APT::Default-Release "unstable";
debian64:~$
Code:
debian64:~# deborphan
libboost-thread1.33.1
libcurl4-openssl
libdns22
libpoppler0c2
libboost-date-time1.33.1
libdb4.2
gstreamer0.10-lame
guile-1.6-libs
The only packages I really recognize there are gstreamer0.10-lame & guile-1.6-libs. I use LAME regularly, and assume that gstreamer0.10-lame has something to do with it; and I know that guile-1.6-libs has something to do with Gnome games.
Code:
debian64:~# apt-cache rdepends guile-1.6-libs

Again the only thing depending on guile-1.6-libs that I recognize as having been purposely installed is gnome-games. I can live without that for a bit, so I will cautiously remove that package identified by deborphan, only.

Verify that it is indeed gone.
Code:
debian64:~# deborphan
libboost-thread1.33.1
libcurl4-openssl
libdns22
libpoppler0c2
libboost-date-time1.33.1
libdb4.2
gstreamer0.10-lame
libguile-ltdl-1
At this point I take some time to verify that my games still work. They do. Now I feel braver, so ...
Code:
debian64:~# deborphan | xargs dpkg --purge

After this, I reboot, do aptitude dist-upgrade, check that games, mp3 players, and other commonly used programs are still working. Everything seems to be functional. I don't really understand it, but it does not seem to have had any negative effects. I'll watch for a few days, and if anything does show up, I will faithfully be back to report it.
