 Just fixed this^. The model was queuing the same indexes waiting for the
image over and over again, so easily hundreds of the same indexes were
queued and once the image arrived, dataChanged(index) was emitted hundreds
of times for single index. Fixed now, the plasmoid is blazing fast when
scrolling with empty cache.

Update the SocialFeed from kde:scratch/mklapetek/socialfeed.

I've started looking into this as well and the empty data actually arrives
to Akonadi's EntityTreeModel, it calls rowsInserted(..) for the new item,
but the data for that particular row is empty. Investigating now.
