[CentOS] rpm/yum/repo issue - Error: Package tuple could not be found in packagesack

Hi guys,

I've been working on a yum repo for PHP 5.2 and today I wanted to update 
it[1], however on a test machine using my PHP packages (e.g. 
php-common-5.2.16-1nux) a yum update to the new RPMs with version 5.2.17 
gives the following error: "Error: Package tuple ('php-common', 'i386', '0', 
'5.2.17', '1nux') could not be found in packagesack".

Any rpm guru around has an idea of what is causing this? 
The php-common package is clearly mentioned in the spec file:
"%package common
