This was caused by freeing the dialpad callback data after clicks.
It should only be freed when the dialpad is destroyed.

This allows us to run the client without installing it our modifying the
environment manually.

Presently This won't work if the client is not installed, unless you manually
compile the schema file and put it in some directory containing
glib-2.0/schemas/, then set XDG_DATA_DIRS to include this directory
as well as /usr/share and /usr/local/share.

Order for loading was reversed

gnome-client startup time when using larger history files (~1500 entries) is
now about 15 times faster.

The setting itself is stored in the daemon (and persists in the config
file), but it is up to the client to use it.
