Well, that happened again. See the backtrace below.
What I did:

1. Removed org-persist-directory folder yesterday
2. Did a quick capture of task (with some embedded checklist) on my
main computer today
3. Went to another computer and refreshed Agenda there, got
questionmarks (org directory is synced between both via iCloud)
4. Went to the problematic buffer and ran backtrace command there,
saved the output

If I delete org-persist-directory again, the questionmarks disappear
(obviously).
