[Not a bug] php notice: $spider_flag, $robotsNoIndex undefined

[torvista]

While upgrading I have been using error_reporting(-1) which has been useful in showing up quite a few errors on my part which would otherwise gone unnoticed.

There are also lots of notices of evidently minor importance but as always I am interested to know more.

For example:

[05-May-2010 21:22:58] PHP Notice:  Undefined variable: robotsNoIndex in ..\includes\templates\template_default\common\html_header.php on line 31

But $robotsNoIndex IS defined in init_add_crumbs.php

This debug error is generated by a refresh of the front page, stock 139b.

Thanks
Steve

ps. $spider_flag comes up with the same error on my front page but I posted before changing the title.

Is it that is being used before it has been defined?

That's a trivial matter that's got no negative side-effects.
It is fixed in v2.0 by virtue of reconstruction.
