Dash Home displays no results (spins forever): "Valid key file could not be found in search dirs": no scopes installed

[Daniel Hahler]

I've upgraded to Ubuntu 13.10 (development) from 13.04.

When tapping the Super key, the Dash appears, but is empty.
When typing anything, the loading indicator spins forever.

unity displays the following on STDERR:

WARN 2013-10-08 22:47:26 unity.glib-gio <unknown>:0 g_settings_set_value: value for key 'visual-bell-type' in schema 'org.gnome.desktop.wm.preferences' is outside of valid range

I had to manually install some scopes, which apparently were not installed by default during the upgrade: unity-scopes-master-default unity-scopes-runner unity-scope-home unity-scope-devhelp unity-scope-gdrive unity-scope-github unity-scope-launchpad unity-scope-manpages unity-scope-sshsearch
