The Debian packaging (downloads.syncevolution.org experimental repos) for
activesyncd is missing the GSettings schema files.  Activesyncd crashes (with a
Trace trap in my testing) when trying to load settings.

Copying org.meego.activesyncd.* to /usr/share/glib-2.0/schemas/ and then
running glib-compile-schemas /usr/share/glib-2.0/schemas/ fixes this particular
problem for me.

I do not know if there are any standard Debian packaging guidelines for
installing GSettings schema files.
