Unfortunately, I really don't know how to fix this bug. Until I can
get a way to reproduce this, it will be very hard to figure out what
is causing this.
My suspicion is that it has to do with redisplay. When Emacs is
redisplaying, it will move window start in a window so that (point)
will be visible in the buffer. For some reason that is a complex
combination of folding text (maybe) and the complex code that Org
evaluates before actually showing an agenda item, it seems that the
redisplay engine might be kicked of with a wrong idea of where point
should be.
In this view, the reason why Samuel is getting this error more than
anybody else would have to do with the fact that he is using HUGE
fonts, with very little text in a window at any given time, so that
the "point is not in the window" condition might be triggered more
often.
These are wild guesses, I know that years ago I spent *many* hours
trying to figure out what is happening her. I still don't know.
What you can do is make me a test case that will reproduce this
behavior, reliably. I think that this problem could depend on hook
settings and on setings of the context-revealing variables like
org-show-hierarchy-above
org-show-following-heading
org-show-entry-below
org-show-siblings
so if you are trying to make a test case, you should use the same
values for these variables and also try to figure out if the current
visibility state of the outline has to do with it.
Also, does this error exist in Emacs 23?
:/
