The problem here lies in the views module. This module makes a call to the t() function which calls a theme function which eventually has to call init_theme() to check which template it should use. Once the init_theme() funcion has been called, the global variable $theme will be set and any other calls to init_theme() will be . Being called so early in time, the init_theme() function has no idea it still has to switch to a custom theme defined by the blocks module.

The fix involves killing a kitten… also know as hacking drupal core. Fire up your favorite editor, open up includes/theme.inc.php and find the following lines of code.

function init_theme() {
  global $theme, $user, $custom_theme, $theme_engine, $theme_key;

  // If $theme is already set, assume the others are set, too, and do nothing
  if (isset($theme)) {
    return;
  }

and replace it with

function init_theme() {
  global $theme, $user, $custom_theme, $theme_engine, $theme_key;

  // If $theme is already set, assume the others are set, too, and do nothing
  // patchy patchy!
  if (isset($theme)) {
  	if(isset($custom_theme)) {
  		if($theme == $custom_theme) {
  			return;
  		}
  	} else {
    	return;
  	}
  }
