-	tag.update_counters tag.id, :taggings_count => tag.taggings.length
+        tag.update_counters tag.id, :taggings_count => tag.taggings.length

 Also, you need to run `rake community_engine:db:migrate:upgrade_desert_plugin_migrations` before you migrate any _new_ CE migrations, to ensure your plugin migrations are listed in the correct table. Please note that you'll have to do this (carefully, and with backups) in production as well. Please post any questions to the CE Google Group.
