You mentioned that you performed a major version update. Did you run 
nepomukcleaner? AFAIK it was recommended. Another thing I can think of is 
running akonadictl fsck or akonadictl vacuum.
If you updated your entire system, did you check whether your storage backend 
(such as mysql) needed some manual update action (mysql_upgrade comes to 
mind).

It also dawns on me : Gentoo used to have sqlite set as the default store for 
Akonadi. This was never recommended by upstream, and completely broke some 
time ago (haven't checked whether it's been fixed). Check that. I switched to 
MariaDB (for Akonadi and Amarok) and have been a happy camper since.
