Fatal error: require_once() [function.require]: Failed opening required 'sites/all/modules/revision_moderation/node.admin.inc'

Recently started getting this error when visiting /admin/content/node/revisions in 6.x-1.0-alpha2:

Fatal error: require_once() [function.require]: Failed opening required 'sites/all/modules/revision_moderation/node.admin.inc' (include_path='.:/usr/share/php:/usr/share/pear') in /usr/local/share/drupal-6.22/includes/menu.inc on line 347

I updated to 6.x-1.x-dev to see if the problem was resolved there, but that didn't help. Did some research and found similar problems in the scheduler module (#952856: Fatal error: 'modules/scheduler/node.admin.inc') that seem to be related to #812636: hook_menu processing should not assume 'file' is inherited.

The attached patch fixed the problem in 6.x-1.x-dev. I'm new to creating patches using git so forgive and advise me if it's not created properly!
