What version of Org are you running?  My version works.  That
apparently empty line is possibly the beginning of the next line.  It
might need a newline.  That is expected.

This is /related to/ a subtle issue in which Org calls an Outline mode
function that is arguably counterintuitive and dangerous.  That
function does not include the final newline, which has led to buffer
corruption bugs.  I reported one long ago with sorting in indirect
buffers.  IMO narrowing should always include the final newline, but
it is a potentially involved discussion.

However, having an empty line at the end of your narrowed region is
expected with what I believe the correct narrowing should be, and
actually unexpected with the default way.  So your bug /should/ be
that it adds a spurious extra empty line, not that it corrupts the
next line.  :)

Maybe you added the empty line yourself, and then added text to it
without  adding a newline.

I hope that helps.

I am interested off-list in the origin of your name, if it has meaning.

Samuel

I've installed org-7.8.11
Now there's no flooding up of next line.
But original buffer is still edited incorrectly.

I even found org-indirect-buffer-display variable.
But still when I kill indirect buffer I have to press Tab several times
to make Org-mode specific things look fine.

I believe the problem is about indirect buffer editing:
modified part is inserted into view-precomposed data incorrectly.
