[bug] category URL if you put /0 (zero) at the end php error occurs

Firstly thanks to the creator of Atahualpa, its a fantastic theme.

I have found a bug:

On a category URL if you put /0 (zero) at the end of the url an error occurs:

i.e.

http://wordpress.bytesforall.com/category/themeframe/0

Warning: reset() [function.reset]: Passed variable is not an array or object in /home/wordpres/public_html/wp-includes/query.php on line 2934

Warning: reset() [function.reset]: Passed variable is not an array or object in /home/wordpres/public_html/wp-includes/query.php on line 2934

Warning: Cannot modify header information - headers already sent by (output started at /home/wordpres/public_html/wp-includes/query.php:2934) in /home/wordpres/public_html/wp-includes/pluggable.php on line 934

I have tried it on a few Atahualpa themed sites with the same results/

Any idea of what the issue is please - doesn't seem to do it on other wordpress sites that are using other themes.
