Comment 5 for bug 772265

I'm not a big friend of the idea to allow someone else than the daemon itself modify config files like datasources.(pickle|json), because this would require the daemon to watch-out for changes to all config files it and its extensions are using.

libzeitgeist and the datahub should instead defer any communication to the daemon until before the first event is inserted, e.g. the datahub should register itself as a datasource only once it inserts the first event. This doesn't necessarily solve the initial issue of this bugreport (zg slowing down login time) but it's a start. In a next step we have to make sure that the datahub inserts events as late as possible, *not during session login*.
