file_db_data is no database. There Akonadi stores all items above 4 KiB 
(aka standard value of SizeTreshold), items smaller it stores in the 

Issues seems to be:

- Akonadi produces duplicates in file_db_data (exactly the same file several 
times) after a while.

- Akonadi seems to loose reference for some of the files after a while so 
that akonadictl fsck which checks file_db_data references moves files into 
file_lost+found. It did to with >100000 here already. Thus cleaning up 
there seems broke.

- Caching that much for an IMAP without offline saving or even for a POP3 in 
local maildirs just does not make much sense.
