Tim thanks for confirming that this may be an issue with the latest Emacs
version, I will try what you suggest and also see if I can track down the
related byte compilation bug.

Exporting tables from python code block: Wrong type argument: markerp, nil

[Darren Syzling]

I'm not sure whether this is an issue with orgmode or my recent Emacs
build, I'm struggling to export orgmode tables from a python code block to
html/pdf.

Version info:
orgmode 9.5.4
GNU Emacs 29.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.20, cairo
version 1.16.0) of 2022-07-29

Note my Emacs is a custom build with native compilation, json and GTK
support - which may be an issue - i.e. taken straight from the latest code
in github.

My simple test case would be something like:

#+begin_src python :results value raw :exports both
  import pandas as pd
  from tabulate import tabulate
  df = pd.DataFrame({'A': [1, 2], 'B': [3, 4]})
  return tabulate(df, headers=df.columns, tablefmt='orgtbl')
#+end_src

If I execute the code in the editor the org-mode table appears in the
results. If I export to html or pdf I get the
error: org-babel-insert-result: Wrong type argument: markerp, nil.

Even a simple example such as the following fails to export but will show
inline.
#+begin_src python :results table :exports both
   return [['A', 1], ['B', 2]]
#+end_src

Stack trace on failure is below - hence why I was concerned with the custom
Emacs build:
