Problem with toc in some exported wiki documents for IDP3

[Rod Widdowson]

Looks like the toc: macro is broken - this is discussed endlessly in the Atlassian JIRA.

See for instance

https://jira.atlassian.com/browse/CONF-27340
https://jira.atlassian.com/browse/CONF-25584
https://jira.atlassian.com/browse/CONF-31467

None of these are exactly the error that this one gives (which is *inside* the PDF btw), but the fact that there are so many isn't
totally hopeful.
