Problems when updating to sphinx to 4.1.2 on readthedocs

[kolibril13]

After updating:

I got this error on readthedocs:

Exception occurred:
  File "/home/docs/checkouts/readthedocs.org/user_builds/flyingframes/envs/latest/lib/python3.8/site-packages/nbsphinx.py", line 2151, in depart_codearea_latex
    assert 'Verbatim' in lines[0]
AssertionError
The full traceback has been saved in /tmp/sphinx-err-8zrn16tf.log, if you want to report the issue to the developers.
Please also report this if it was a user error, so that a better error message can be provided next time.
A bug report can be filed in the tracker at <https://github.com/sphinx-doc/sphinx/issues>. Thanks!

any ideas?

Duplicate of #584, can you please check if #591 fixes this for you?

like this, right?
edit, no, that seems to be wrong:

The latest nbsphinx release should fix this.
