Importing space backup causes HibernateSystemException - not-null property references a null or transient value: com.atlassian.confluence.pages.Attachment.fileName

I get this error when restoring a space into 1.3DR4 from a 1.2.3 export. Other space exports - with attachments - restore OK.
Please email me to get a copy of the export zip file - the content is proprietary.

Cause:
org.springframework.orm.hibernate.HibernateSystemException: not-null property references a null or transient value: com.atlassian.confluence.pages.Attachment.fileName; nested exception is net.sf.hibernate.PropertyValueException: not-null property references a null or transient value: com.atlassian.confluence.pages.Attachment.fileName
