Thanks! Can you point me to (or attach) the Sphinx project that triggers this bug?

It's a 400 pages private repo on gitlab, I have no idea why this happens but I figured that class attribute must resolve in its own instance if asked. But... should not be asked as it already is a content flowable state itself so it would make no sense to ask.
I can give you access to the private repo.

Having this problem also. Also a large, multi page document (private repo also and sadly can't share it).
The error occurs not every time but is dependent on the page content and page breaks, so moving test around on the source pages fixes the issue temporarily.
Using the fix above this is fixed. Any chance this makes it to the next release?

My fix is quite a bazooka to just let the program continue. I think there is an underlying problem which should be addressed instead: it makes no sense to ask what is the flowable state of a flowable state... I would at least raise a warning.

@mythsmith Can you provide me access to the private repo? Or a minimal Sphinx project the reproduces the issue would be just as good. Thanks!

@brechtm just saw your comment now, I never log in here: the repo would be on gitlab, do you have an account there?
