[BUG] When calling org-tree-to-indirect-buffer: (wrong-type-argument listp org-fold-outline) in org-fold-core-get-folding-spec-from-alias [9.6.6 (release_9.6.6 @ /gnu/store/c7vqk20kf6zw73klr8bacnh0gqahk5dd-emacs-29.1-29.1/share/emacs/29.1/lisp/org/)]

Hi,

Since upgrading to Emacs 29.1 and Org 9.6.6, I am getting an error when
opening a bookmark to an Org subtree buffer created with burly.el.  When
opening the bookmark, burly calls org-tree-to-indirect-buffer to make a
new indirect buffer showing the subtree in question.  This worked fine
in Emacs 28 and the previous Org version I was using, 9.5.something,
IIRC.  Now I get this error (please see the attached backtrace, which is 
abbreviated, and some functions were re-evaluated so as to be interpreted).

FWIW, I also tried setting org-fold-core-style to overlays and
restarting Emacs, but the error still happens, although with a different
symbol in place of org-fold-outline.

Thanks for your work on Org.

Adam
