[BUG] org-clock-display is partial (only some entries are counted)

[Sebastien Vauban <sva-news-D0wtAvR13HarG/iDocfnWg@public.gmane.org>]

Hello,

As you can see on http://screencast.com/t/B0knccOCqco, the output of the
command org-clock-display (bound to C-c C-x C-d) -- which displays
subtree times in the entire buffer -- is partial: for a reason which
still escapes me, meetings A and B are not counted...

On the other hand, the dynamic block (at the bottom of the ECM) is
correct.

PS- Another weird thing is to see that "Org clock display" reports some
    time (0:13 in the screenshot) for the section "Worked Hours
    Report"... which has no LOGBOOK!
