In Sphinx 1.1.3 there's a bug. Here's a way to reproduce this:
source/
nested/
index.rst
a.rst
index.rst
b.rst
in source/index.rst:
:toctree:
nested/index
b
In source/nested/index.rst:
:toctree:
a
If you render this the first time, in nested/a.html you see a correct link to b.html, and vice versa. Edit a document and see the next/previous links disappear. Edit conf.py (change theme for instance) and re-build html. The links are back again. Touch a single rst file, and they disappear.

I was unable to reproduce the problem.
Have you tried deleting the cached environment (everything under the _build directory) to force a fresh build?
If the problem persists, can you attach a copy of the source directory?

I could not reproduce the problem, too.
Althought this is old and closed, I would like to say that I had the same problem which was resolved by deleting _build cache as you suggested.
