Yes some how this got mislabeled.

Yes, I ran the restorecon command as you described it
('restorecon -R
-v ~/.pki') and things were fine again. So I guess my .pki settings
were wrongly changed at some point in the past, right?
I'll keep the setsebool method for the next time chrome breaks, I'm
afraid in a few updates.
Thanks,

Did you run the restorecon command?
It looks like chrome is allowed to read files labeled home_cert_t
but might be blocked form other types.
You could also turn off the chrome security using a boolean
setsebool -P unconfined_chrome_sandbox_transition 1
Which would do the equivalent of what you did in relabelling the
executable to bin_t.
