That's one of the symptoms but not the only problem. I have cleared the
akonadi cache more than once. So non existing emails/folders don't show up in
clean akonadi folders.
Putting emails in non existing folders will probably cause data loss by the
way so be careful.
There are many issues here:
1) emails get filtered twice for some reason and thus appearing twice in
2) some race condition in updating the akonadi database because on occasions,
the extra copy only appears for a split second then immediately disappears.
3) possibly many other reasons.
