Installation of eZ Studio using php ezpublish/console ezplatform:install studio command throws SQL import error. This is because DemoBundle database structure was updated (https://github.com/ezsystems/DemoBundle/commit/47153529027cb85869ae27ed0e493e5bf1d07e0a) and contentclass_attribute width ID=336 is now used by Almighty's RichText field. eZ Studio SQL import script should be updated as well.
