Gievn the error message I'd say you have the i18n and i18n-support plugins installed. These plugins are no longer required since Griffon 1.1.0. Uninstalling the plugins will solve your problem.
The reason is that the functionality provided by those plugins is now available in Griffon core since 1.1.0, so those plugins create a conflict.
