Wrong parameter count for debug_backtrace() in devel_themer_catch_function()

For anyone else stuck with PHP 5.2.4 with no easy way to upgrade for the moment, I got devel_themer working at the suggestion of the post above. In devel_themer.module, change:

function devel_themer_init() {
  if (user_access('access devel information')) {
    // Add requisite libraries.
    drupal_add_library('system', 'jquery.form');
...

to

function devel_themer_init() {
  if (user_access('access devel information')) {
    define('DEVEL_THEMER_PARAM_MINIMUM_PHP', '5.2.5');
    // Add requisite libraries.
    drupal_add_library('system', 'jquery.form');

and

function devel_themer_catch_function() {
  $trace = debug_backtrace(FALSE);
  $hook = $trace[1]['args'][0];

to

function devel_themer_catch_function() {
  $trace = (version_compare(phpversion(), DEVEL_THEMER_PARAM_MINIMUM_PHP) < 0) ? debug_backtrace() : debug_backtrace(TRUE);
  $hook = $trace[1]['args'][0];

Current Drupal 7 requirements suggest that it should run with PHP 5.2.4, as at http://drupal.org/requirements#php :

Drupal 7: PHP 5.2.5* or higher (5.3 recommended)

*For Drupal 7, versions of PHP 5.2.4 that include backported security patches also meet the requirements. The PHP version included with Ubuntu 8.04 is the most common example of this.

Rolled a patch with these edits to include in drush make files.
