Thomas,

Could you provide a recipe? As a test, I ran Emacs with just the following
code in my .emacs:

(require 'saveplace)
(setq-default save-place t)

(setq org-show-siblings '((default) (isearch t) (bookmark-jump . t)))

Emacs ran without any errors, and I made a test.org file, created multiple
headlines, and left point in the middle of a paragraph. Everything restored
fine after closing and revisiting the file.

I was hoping someone else would jump in and interpret those debugging
messages, because I'm not proficient enough in Emacs Lisp yet, nor familiar
enough with the org-mode code base. All I can do is try and reproduce your
error. The code seems to be robust, though.

Tried my best with what I have,

This doesn't work for me:
