(Un)publish all documents in folder breaks the workflow if there are documents in another state

Run the archetype:

mvn archetype:generate \
-DarchetypeRepository=http://maven.onehippo.com/maven2 \
-DarchetypeGroupId=org.onehippo.cms7 \
-DarchetypeArtifactId=hippo-archetype-website \
-DarchetypeVersion=1.09.00

$ mvn package && mvn -Pcargo.run

Login to the CMS with the admin user
Go to the news/2011 folder and unpublish one of the articles
Now select the action menu on the 2011 folder and select the 'take all offline in folder'
Press OK and see the error message appear.

See the screenshots.

This seems to be a regression based on the new document model where the variants stay instead of getting removed.
