Errors after updating to rc1 and running update.php

I just updated Rules from 6.x-1.0-beta5 to 6.x-1.0-rc1 and got the following errors after running update.php. Not sure whether I should be worried or not but thought I'd better mention it.

* warning: include_once(./sites/all/modules/rules/rules/rules.rules_defaults.inc) [function.include-once]: failed to open stream: No such file or directory in /home/finalcut/public_html/sites/all/modules/rules/rules/rules.module on line 946.
