Here is some additional information that could help to narrow the number of possible reasons down a little bit (at least I hope so).
The following packages were upgraded right before gnome-settings-daemon stopped working: gstreamer0.10-esd 0.10.16-1 -> 0.10.16-2 gstreamer0.10-plugins-bad 0.10.13-1 -> 0.10.14-3

xscreensaver-gl-extra 5.05-3+nmu1 -> 5.10-2 xsltproc 1.1.24-2 -> 1.1.26-1 As I mentioned earlier a downgrade of libglib2.0-0 to version 2.20.0-5 brought back some life signs of gnome-settings-daemon again, but this procedure broke a bunch of other packages that already depend on libglib2.0-0 >= 2.22 and therefore only served as a temporary test. As the gnome-settings-daemon version now differs from many of the other gnome components (2.26 vs. 2.28) I suppose a new version of g-s-d could solve the issue?
