i copied the whole warning buffer after an error was triggered.

i had another go:

- i made a purely lorem ipsum org file (can share if needed)
- loaded a minimal emacs config (the one i use for testing/debugging mastodon.el, can share)
- loaded a really minimal org config (can share if needed)
- loaded the org file
- repeated the already mentioned steps, triggering the error.

with this test file, when the error is triggered, the way the file breaks is that a second-level TODO heading is split after the first star, becoming a top-level heading with a single star on a previous line (often, not sure if always, i think other breakages happen also, with my original file other breakages happened).

a backtrace is below.

sometimes the warnings buffer gets subsequent information added to it, but i gather that's because we continue operating with a borked file. the backtrace below is a copy of the whole warnings buffer after only one error was triggered.
