I can see this happening if the kindle is being smart, noticing the extension on the URL, and doing something special.

My PHP is set up to use cookies.

I can imagine this causing some errors and, even worse, write something to the HTTP stream. The latter would prevent writing the headers needed for downloads to succeed, explaining the problem you see. Try commenting out the body of dprint (utilities.php, at the end) and see if the weird errors and/or the kindle problem go away.

Commenting out the body of the dprint function made no noticeable difference.
However, after tweaking some of the FastCGI parameters for my Nginx server... I seem to have everything working fine, now. Including the internal authentication and file downloads (with the dprint function). Bumping up various fastcgi timeouts, buffers, busy buffers, and adjusting the temp file write size seemed to do the trick.
I'll let you know what else I run into.
