May be related to this bug? https://jira.atlassian.com/browse/CONFSERVER-38682

I can confirm the bug. I suspect that since Confluence uses the syntax { ... } to identify macros, this bit of text is somehow getting processed as a macro with no body causing Confluence to throw an error.

Fixed in 3.1.1
