I've determined this is caused by file access from QML in the avatar
cache . It's actually significantly faster using remote URLs for the
avatars. Using the remote URLs also means QML will handle local caching
of the avatars for us, so we don't need to manage the avatar cache in
the backend at all. The only remaining need for a cached version of the
avatar is the notify-osd integration, which doesn't support a url to a
remote image.
For now we'll drop the avatar caching logic from the friends dispatcher
and start storing the URLs in the model. However, the dispatcher will
need to cache an avatar long enough for the notification. Perhaps cache
in /tmp which will get purged on restart?
