Problem could be broken cache when You run game not properly patched. If this game during launch, copy some data from patch dir to cache and validate it later, You break it just by launching game.
For a test, go to file manager and rename this cache to something else (i.e by adding "_old" at the end of it's folder name) and launch game again, which should install game again. And do not rebuild database meanwhile as You will have two exactly the same meta data resources and I don't know what PS3 would do in such case (can i.e freeze, and restart can break filesystem table which would You put into more serious troubles :P).
