Error on install
I just attempted to install via the normal web UI for the first time in a very long time. Brand new D7 site, brand new Civi. Disabled all components but CiviEvent and CiviMail. On install, I received this message:
CRM_Extension_Exception_DependencyException: Cannot disable extension due to dependencies. Consider disabling all these: civi_campaign,civi_case,civi_contribute,civi_member,civi_pledge,civi_report,financialacls in CRM_Extension_Manager->disable() (line 387 of /var/www/mysite.org/web/sites/all/modules/civicrm/CRM/Extension/Manager.php).
Reloading the page got me past the error but since it's the first thing a new admin will see it's worth fixing IMO.
