[php-maint] Bug#491928: libapache2-mod-php5: AddType directive misusage

[Andrey]

Package: libapache2-mod-php5
Version: 5.2.6-2
Severity: important
File: /etc/apache2/mods-available/php5.conf

Hello maintainer!

I've just spent some 2 hours trying to find out why no PHP script
works for me. It kept failing with a cryptic Apache log message:

  Premature end of script headers: example.php

It appears that the problem was in
/etc/apache2/mods-available/php5.conf:

  <IfModule mod_php5.c>
    AddType application/x-httpd-php .php .phtml .php3
    AddType application/x-httpd-php-source .phps
  </IfModule>

When I replaced AddType directives with AddHandler directives,
everything started to work nicely:

  <IfModule mod_php5.c>
    AddHandler application/x-httpd-php .php .phtml .php3
    AddHandler application/x-httpd-php-source .phps
  </IfModule>

I'm not an Apache nor PHP expert, so let a more a more competent
people speak for me (excerpt from
http://wooga.drbacchus.com/why-we-dont-like-php):

  AddType associates a Content-Type with a file extension, and that
  tells the browser how to deal with a particular data
  stream. AddHandler, on the other hand, maps a handler to a file
  extension.

  Stated more simply, AddType tells the browser what to do with a
  file, and AddHandler tells the server what to do with a file. PHP is
  handled by the *server*, not by the browser, and so AddHandler is
  more appropriate.

Please correct me if I'm wrong but it seems that we should really use
AddHandler directives there, not AddType.

I'm ready to provide any additional info.
