Call to undefined function rules_get_items() on updating from 1.3 to 1.4

I get the same problem after installing Drupal Commons and then hitting drush up.

Looks like hook_menu() of rules_admin is invoked although its dependency "rules" is not there. Sounds like it would be caused by the (unknown) underlying problem causing #903246: Fatal error: Call to undefined function rules_include().

This is the traceback I get when trying to install/update to 1.4 (as well as -dev) with drush:

The external command could not be executed due to an application error. [error]
Drush command terminated abnormally due to an unrecoverable error. [error]

Close due to long inactivity. Please don't hesitate to re-open if the issue is still relevant.

For what it's worth: I got this error when trying to uninstall rules_admin via Drush. At that point, I had already disabled the rules module. So I re-enabled the rules module, then I was able to uninstall rules_admin, and finally the rules module itself (all via Drush). Hope this helps somebody.

It helped me, thanks!
