Brad showed this bug to me during the meeting, and my theory as well is that 
this is a serializer bug. On body retrieval you do not report the mail 
headers again AFAIU, which apparently causes the serializing code to delete 
the header part from the Akonadi cache.

The serializer plugin is in kdepim/akonadi/plugins. The bug might as well be 
generic though, possibly in the  classes ItemSerializer and/or ItemModifyJob 
in libakonadi.
