For me it's just the one account. Another one works fine.

I can restart the agent from akonadiconsole, and that makes it sync, but then 
it hangs at what seems to be the end of the sync.

I'm not so sure about restarting akonadi proper. I just tried it and it seemed 
to work, but given that I've restarted the machine several times since this 
phenomenon started, and invariably the same problem appears, I don't think 
that fixes it permanently, if at all.

If you can be specific about what I need to do, I can try to provide more 
information.

Ironically, the account that works fine has many, many more messages in its 
folders than this one.
