This is an incomplete initial bug report.  I don't have time right now to
chase down all the details.

A couple of times in the past month, the subheadings in the org file I'm
working on (with lots of org-babel code blocks) disappear.  <TAB> does not
fold or unfold those headings, although the indicator (...) still shows.
In desperation, I switch to fundamental-mode, but the text is still not in
the buffer.  I save the buffer under a different filename to find that all
the missing text is in the file.

Has anyone else seen this?

summary:
1. subheading text disappears from org file, even in fundamental
2. saving the buffer shows that the disappearance is cosmetic only
3. I have not established reproducible conditions for this yet.
