--- Comment #10 from Alexander Troshchenko <[email protected]> ---
Importance of the bug:

 In the test-case above, 32% of the document is missing in the working feature.
This is bad as PDF's are popular in use among businesses to avoid formatting
losses and unwanted changes in multinational companies. However, this bug
requires to meet several conditions in order to appear, what reduces importance
of it as it is not that easy to replicate. I wouldn't consider solving the bug
unless fix worth chances to meet enough people making 250-320 pages in several
insertions and exporting as PDF.


Possible cause:

Because Bug appeared in 215 pages as described by the poster and in 298
test-case, I guess there is a trigger that changes the algorithm of page
rendering (for efficiency purposes? ). It probably should be triggered at
smaller pages amount than now. However, I didn't see the code, so my underlying
cause is a guess that is based on various tests that I've done on documents on
my machine. The fact that the disappearing page is 127 (Top boundary of signed
byte) makes  me think that there is a byte used somewhere, where it shouldn't
be used. But this requires further testing.

The sure thing is that the bug doesn't appear unless you do insertions, what
makes me think that underlying problem is in exporting insertions code.
