Description

I get a Content Encoding Error if symfony throws an exception in the production environment with compression turned on.

This seems to be directly related to the compression as it is the only setting value that causes a problem.

prod:
  .settings:
    no_script_name:         on
    logging_enabled:        off
    
staging:
  .settings:
    web_debug:              on
    no_script_name:         off

dev:
  .settings:
    error_reporting:        <?php echo (E_ALL | E_STRICT)."\n" ?>
    web_debug:              on
    cache:                  off
    no_script_name:         off
    etag:                   off

test:
  .settings:
    error_reporting:        <?php echo (E_ALL | E_STRICT & ~E_NOTICE)."\n" ?>
    cache:                  off
    web_debug:              off
    no_script_name:         off
    etag:                   off

    check_symfony_version:  off       # Enable check of symfony version for every request. Set to on to have symfony clear the cache automatically when the framework is upgraded. Set to off if you always clear the cache after an upgrade.
    compressed:             on       # Enable PHP response compression. Set to on to compress the outgoing HTML via the PHP handler.
    check_lock:             off       # Enable the application lock system triggered by the clear-cache and disable tasks. Set to on to have all requests to disabled applications redirected to the $sf_symfony_data_dir/web/arrors/unavailable.php page.

    # Output escaping settings
    escaping_strategy:      on        # Determines how variables are made available to templates. Accepted values: bc, both, on, off. The value off deactivates escaping completely and gives a slight boost.
