[Pkg-nginx-maintainers] Bug#844427: nginx-extras: download failure with all Android browsers when mime-type is set properly

[Dan Ritter]

Package: nginx-extras
Version: 1.9.10-1~bpo8+4
Severity: normal

Dear Maintainer,

   * What led up to the situation?

nginx is set up to serve /home/user/public_html as url:~user/
via

    location ~ ^/~(.+?)(/.*)?$ {
                alias /home/$1/public_html$2;

This generally works.

However, when I set the MIME type for epub files:

     types {
         application/epub+zip                  epub;
     }

Then downloads of files with names containing [ or ] characters
fail on Android Firefox and Chrome browsers. They complain of
an illegal character in the URI, which I suspect means that nginx
is not properly uri-escaping the filenames.

They do not fail on Debian Firefox and Chrome browsers.

If I remove the mime-type listing for these files, it works smoothly on
all tested browsers.

(Is this, perhaps, actually an Android problem? Maybe, but there ought
to be a workaround at the server end.)

I have observed the same problem on nginx, nginx-extras and nginx-fancy,
including shifting to the jessie-backports version.
