[O] Bug in pdf export of tables with latest development version

[Herbert Sitz]

I'm having problems exporting to pdf with a source block that generates a table
result.  If the table has enough rows to get to bottom of page, it seems, the
rest of the table output disappears/is discarded and the pdf document skips to
text after the source block output.

Everything works fine with html output.

Here's sample code.  With repeat number of above 50 or so it will truncate table
output in resulting pdf:
--------------
* Head one

#+begin_src python :exports results :results value
mylist = []
for i in range(100):
    mylist.append([i,i+1,i+2,i+3,i+4])
return str(mylist)
#+end_src

#+results:

* Head two
more text for head two
