Laggy adjustments and inexplicable logs

[tch]

Using OLPC-AU testing build [1] and Sugar 0.102 packages, you will notice that when using the frame palette Gtk.Adjustment such as sound-volume and or speech-pitch, it takes a considerable amount of time to update the UI.

Also, when this happens, the log is spammed by collaboration related errors such as:

1396958323.932242 DEBUG root: __nick_changed_cb
1396958323.959951 DEBUG root: __jabber_server_changed_cb
1396958324.021701 DEBUG root: homebox: reassigning list view index to 1
1396958324.033643 DEBUG root: _Account.__account_property_changed_cb dbus.ObjectPath('/org/freedesktop/Telepathy/Account/salut/local_xmpp/account0') None None

and

1396958324.535489 DEBUG root: _Account.__account_property_changed_cb dbus.ObjectPath('/org/freedesktop/Telepathy/Account/gabble/jabber/_31c4a1019c2e09bb50a59980b3082ae4848f1f248_40jabber_2esugarlabs_2eorg0') None None

1396958324.679251 DEBUG root: _Account.__account_property_changed_cb dbus.ObjectPath('/org/freedesktop/Telepathy/Account/salut/local_xmpp/account0')

I am able to reproduce it, consistently, on a XO 1.5. With the corresponding image at [1].
