Fatal error: Call to a member function getName() on a non-object ... devel_themer.module on line 339

Hi,

I am using Drupal 6.x, views 2 and enabled the frontpage view, as well as panels 2, to promote a node to the front page, and I intend to use front-page.tpl.php in order to theme it differently. I am also using the devel module, the zen theme, and the zen classic sub-theme where I put the front-page.tpl.php in the subtheme folder. I'm getting the following error when I visit the front page of my test site.

The error I'm receiving is described below, and I really don't have the PHP know-how or the time to debug it fully. Anyway, here are the details. It seems to be a panels related issue/problem. I know it isn't a devel problem per se, but in the devel module the problem occurred and it's somehow related. However, its apparent it is a panels issue. Since I've created everything on a fresh install of a test site, I know it isn't improper use of a theme or a view or something. The problem description follows below.

I want to use a sub-theme, and apparently it doesn't like a sub-theme. Unfortunately, if I cannot correct this error I might have to give up using the sub-theme feature in drupal 6. Can anyone help?

Thanks!
Moses

This is the error I received:

Fatal error: Call to a member function getName() on a non-object in C:\xampp\htdocs\sites\all\modules\devel\devel_themer.module on line 386

================================================

I used the following debug code after the line in which the problem occurred. The code is:

// Check for a bad theme call (see http://drupal.org/node/237056).
if ($i == count($params)) {
// Find the offending theme call
$debug = debug_backtrace();
drupal_set_message(count($args) . " arguments were passed to theme('$hook', ..) but it was only expecting " . count ($params) . ". Please debug the code that invoked theme('$hook', ..). Further debug info follows." . print_r($debug[4], TRUE) . print_r($meta, TRUE) . print_r($info, TRUE) . '', 'error');
break;
}

================================================

I received the following output when I refreshed the page:

5 arguments were passed to theme('panels_default_style_render_panel', ..) but it was only expecting 4. Please debug the code that invoked theme('panels_default_style_render_panel', ..). Further debug info follows.

=======================================================

The file display-render.inc where the problem actually began contains the following offending function that generated the error:

return theme($style['render panel'], $display, $owner_id, $panes, $style_settings, $panel);
