Why does it still call transaction items with transaction support turned off?

I am pulling my hair out here (and I don't have much to spare.)

I changed Line 22 of test_helper.rb to read:   self.use_transactional_fixtures = false #trying to get things to work

However, I am still getting the following error when I run the task unit test. (source at bottom of message)

  1) Error: test_create_read_update_delete(TaskTest): SystemStackError: stack level too deep     /Users/alan/Projects/superb/vendor/plugins/acts_as_taggable_on_steroids/lib/acts_as_taggable.rb:220:in `reload_without_tag_list'     /Users/alan/Projects/superb/vendor/plugins/acts_as_taggable_on_steroids/lib/acts_as_taggable.rb:220:in `reload'     /Users/alan/Projects/superb/vendor/plugins/betternestedset/lib/better_nested_set.rb:161:in `before_destroy'     /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/callbacks.rb:322:in `send'     /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/callbacks.rb:322:in `callback'     /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/callbacks.rb:294:in `destroy_without_transactions'     /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/transactions.rb:104:in `destroy'     /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/connection_adapters/abstract/database_statements.rb:66:in `transaction'     /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/transactions.rb:80:in `transaction'     /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/transactions.rb:100:in `transaction'     /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/transactions.rb:104:in `destroy'     ./test/unit/task_test.rb:29:in `test_create_read_update_delete'   /Library/Ruby/Gems/1.8/gems/activesupport-2.0.2/lib/active_support/testing/default.rb:7:in `run'

I am TRYING to be good and run tests, but since this works in the actual code but FAILS in my testing, it is discouraging me from writing more tests. ANY help would be GREATLY appreciated...

Thanks!!
