I can't see anything in patch-136 that would lead to this error.  But I
do know that there is a problem in the relationship between
planner-appt and planner-trunk.

Just so that I can confirm that this is the problem
you have, can you tell me when was the last time you updated your copy
of planner [i.e., the last patch level] before patch-136?

The problem, briefly, is that planner-trunk-tasks moves point away
from the newly created task, and it is difficult reliably to find that
task to parse it for appointments.

I have an idea about how to fix this, but I don't have the time to do
it at the moment as it is rather involved.  I could post the details
of what I think needs to be done if someone else wants to have a go.

In the mean-time I think that it would be possible to work around this
by using after-advice to planner-create-task instead of a hook: remove
planner-sort-tasks-maybe from planner-create-task-hook and add
something like this:

(defadvice planner-create-task (after my-sort-stuff activate)
  (planner-sort-tasks-maybe))

[assuming that you keep the trunking advice for
planner-sort-tasks-maybe].  I haven't tested this, but I think it
ought to work.
