Thanks for the fine report.  Unfortunately, I can't reproduce this since
the text following "Top level" is hidden here.  foo.org appears as


# -*- mode: org; -*-

#+STARTUP: logdone
#+TAGS: bb(b) dw(d) holiday(a) meeting(m) note(n) q(q) releng(r) sysadmin(s) 
eng(e) other(o)

* Top level


If I manually insert its text into a new buffer foo.org. the buffer after
step (3) looks like


# -*- mode: org; -*-

#+STARTUP: logdone
#+TAGS: bb(b) dw(d) holiday(a) meeting(m) note(n) q(q) releng(r) sysadmin(s) 
eng(e) other(o)

* Top level
** second level 1
*** third level 1                                                         :b:
    CLOCK: [2011-07-10 Sun 12:44]--[2011-07-10 Sun 12:44] =>  0:00

** second level 2
*** third level 2                                                 :meeting:b:
    CLOCK: [2011-07-10 Sun 12:46]

material for third level


which is probably the expected behavior.  What shall I do?

Chong has fixed some silliness in that code, so maybe this has been
fixed already.  Please upgrade.

If the error persists, could you try to edebug `display-buffer' before
org calls it and tell me the value of "normalized" calculated in these
lines:

         (normalized
          ;; Normalize specifiers.
          (display-buffer-normalize-specifiers buffer-name specifiers label))

Thanks, martin
