I'm using customize themes that include many, many font lock faces;
other than that no.

I don't know. It only happens after periods of days using emacs, and i
cannot afford that long without my customizations and other packages.

Yes, it does.

Sounds reasonable, specially since font-lock-fontify-buffer still works.
For now, i'll apply Stephan's advice and try to see if i reach the
condition with font-lock-support-mode disabled.
Thanks!

There are two ways to write error-free programs; only the third one
works.
