Subtheme _preprocess_hook's being run twice ? [#253599]

Well this is a really wierd one, that I was drawn into after seeing comment zebra classes always being marked "even" in my subtheme. I'm hoping someone has some advice of where to look next.

Basically I'm seeing a hook like phpthemplate_preprocess_page being run twice for my sub themes and the Zen Classic example. I've been verfiying this by putting drupal_set_messages in the hooks and looking in the "Theme Registry" via the Devel module.

This doesn't happen with the core Zen theme where phpthemplate_preprocess_page is called once as expected.

I see this with other preprocess_hook's as well, like my comment hook overide being double-executed leaving me with all "even" classes for comments.

Could someone give me a pointer where to look next? I assume phptemplate_preprocess_page() should only be called once for a subtheme, correct?

Thanks!

On further review, the core Zen _preprocess_hook's are double executed for any .tpl.php templates that a sub-theme has defined. For example I have comment.tpl.php in my subthemes, so phptemplate_preprocess_comment() is called twice for every comment.

Changing this to a "bug", feel free to change it if I'm alone on this.

I see this weekends commits included one that moves the phptemplate hooks to be zen hooks:

http://drupal.org/cvs?commit=113980

However, in Zen's template.php only theme_breadcrumb() seems to have been changed to zen_? (both calls in template-menus.php were also updated)

Is this on purpose? Only reason I'm asking in this thread is that I think it pertains to why I'm seeing double calls for phptemplate hook calls on subthemes with their own tpl files.

Thanks!
