Sparky MATE comes with several packages from MATE 1.4 which are considered deprecated for some time now, namely:
While mate-corba was substituted for dbus which is already installed, so the former can probably (just my guess) be purged, I am not so sure about the mate-conf-bunch. http://wiki.mate-desktop.org/mateconf_to_gsettings
is very confusing for me and I don't even know whether it is meant for me or only for programmers.
Looking at the values in mate-conf-editor it seems to me that they are not used but remnants. For example /apps/control-center/appearance/more_backgrounds_url refers to art.gnome.org whereas dconf-editor in org/mate/control-center/appearance/more-backgrounds-url correctly names mate-dektop.org. My changes to the appearance of caja are to be found in dconf-editor but not in mate-conf-editor.
According to http://mate-desktop.org/blog/2013-04-02-mate-1-6-released/index.html
"All other settings will be migrated if you have MateConf 1.4 installed." it should be possible to purge the mate-conf-bunch without negative side-effects.
Does anyone know for sure?
