That's kind of looking like an out-of-date third party package, though
it's hard to be sure. You mention upgrading your system, and Emacs was a
part of that system upgrade, right? (Meaning, you're not running Emacs
from its development repository?)

Try running M-x toggle-debug-on-error and triggering that error again --
that should show us what is calling `nnheader-parse-naked-head'.
