I've just reported the new bug: https://jira.atlassian.com/browse/GHS-11412.

@David Leach, you're correct, it's the .xlsx and .docx attachments that cause the errors, although it appears that it's the case for .zip as well.

I'm also getting this.  Seems related to attachments with a .xlsx and .docx extensions
