bug#25132: 26.0.50; emacs hangs when loading org file with python source blocks

[David Dynerman]

Dear Glenn + bug-gnu-emacs,

Did you try the steps to reproduce? Indeed Clément was right! The bug also 
reliably reproduces also with org 8.2.10, if you additionally set 
org-src-fontify-natively to t.

Please let me know if you need any more information for the bug report,
David
