segfault when opening org-file

Was able to produce under gdb:

[shaleh]

Excellent stack trace.

Can you reproduce it when you load remacs with -Q? That way there are no local customizations at play? If you cannot, please binary search your config to identify what is helping trigger this.

Thank you.

Attempting to load it with -Q and C-x C-f just hung. Trying again with the menu worked.

Ok, I think I've got a minimal init.el:

(eval-when-compile
  (require 'use-package))
(use-package spaceline)
(use-package spaceline-all-the-icons
  :config
  (spaceline-all-the-icons-theme))

and this tmp.org:

test
* this is a test

Then running remacs tmp.org results in the segfault.
