I know it's not much but could you guys please take a look at this
patch (I haven't submitted it trough the reviewboard since it's a
pinpointed change)? It delays calling AccountsModel::load() after
dataChanged() is emitted until the moment there is nothing else to
execute in the event loop. This means that the UI has time to update
after dataChange is emitted (the ledger seems a bit more responsive
when changing the status of a transaction) and after load() does get
executed (hopefully while the user is idle) all the data in the UI
will be correct since the model notifies the view of any data change
during load().
