When you are developing the fixes for Google+, can you be aware it seems to be copying the google+ profile picture on top of the Kunena picture in the Kunena User Manager rather than the other way round.
This I believe is an issue and should not happen - it means that even when the User map is removed, it still doesn't default back to the Joomla picture as its overridden.
I can get an avatar back by adding the avatar manually (obviously) or logging in in Facebook .- This also seems to be overriding Kunena. I have got the enable profile picture set to Joomla and the Link pic to social profile set to Yes.
I expected the JFBConnect User Map to contain the profile picture, but in neither case did I expect it to update another component.
Is that what you expected?

The 4 pictures I have shown are
i) the Login box after G+ login (no profile pic),
ii) Kunena after the G+ logon,
iii) showing the JFBConnect User Map (which I then delete),
iv) then after logging into the site with facebook the Kunena Profile picture is updated.
