I recently set up Phabricator for a personal project.
I've just created my first task, and when I go to `/T1` it shows me
```
>>> UNRECOVERABLE FATAL ERROR <<<
Call to undefined method PhabricatorActionListView::setDisabled()
/opt/phabricator/src/applications/maniphest/controller/ManiphestTaskDetailController.php:422
┻━┻ ︵ ¯\_(ツ)_/¯ ︵ ┻━┻
```
My `phabricator/` checkout is at 0e8ed0c61684441ceafe2791b9a05970b58babac.
