It is indeed strange.  I generated the backtrace several times over 
several sessions before reporting.  I also can reproduce it in a clean 
Emacs configuration like so:

Using with-emacs.sh on Emacs 29.1:

1.  Run "with-emacs.sh -i burly"
2.  "C-x C-f /tmp/test.org RET"
3.  Input a file like so:

   * Heading A
   ** Heading A1

4.  With point on Heading A1, "C-c C-x b".
5.  "M-x delete-other-windows RET" to show only the subtree buffer.
6.  "M-x burly-bookmark-windows RET", input name, save bookmark.
7.  Kill the file's buffer and delete-other-windows.
8.  "C-x r b" select bookmark that was created, and open it.
9.  You should get the error, and with debug-on-error, the backtrace.

This bug breaks burly's functionality to bookmark and restore subtree 
buffers, which worked fine before upgrading to Emacs 29.1.

Thanks,
Adam
