Well, the one reason I could think of right now is that there must be 
some corrupted journals in there. Can you see if there are any using 
--verify and then moving them out of the journal directory?

journalctl -F vs journalctl --list-boots use different code paths while 
digging through the journal. Afaik, one of them is stricter when it 
comes to interleaving intact and corrupted journals.
