Unexpected Output error with WP 3.2.1

Good thing I didn’t update my live install yet a bunch of plugins including sexybookmarks return errors with WP 3.2.1. All plugins were turned off this error occurs when you activate the plugin “The plugin generated 1 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.”
