ERRORS DURING LOADING:
  • cus-start: Wrong type argument: listp, t

Somewhere early in the emacs loading process, I trapped the above error
through an advice macro I built to time require calls. I wrote the macro
to profile my use-package macros to fix long-standing errors. I fixed
them all in my init.el, except the one above. I do not know how/where
this call originates. I myself do not use or call cus-start directly. I
get this error with both master and unstable sources. Would appreciate
any help/advice.

You must tell more about the problem, like show the minimal init file
which could be used to reproduce the problem.

In general, early-init.el is not supposed to be used for too much
initialization stuff that can be done in init.el.

Anyway, I guess the problem is solved and we can close this bug?
