Trying to uninstall the module via drush results in PHP error.
I then manually deleted the three avatar_selection tables and tried to re-enable the module,
but for some reason the tables don't get re-created.
avatar_selection.info reads 2012-02-12
PHP Fatal error: Call to undefined function file_create_path() in /var/www/drupal/sites/all/modules/avatar_selection/avatar_selection.install on line 121
