Import fails using DOM parser: "Cannot deactivate indexing as it is not currently active."

If jira-application.properties is copied verbatim from a previous version of JIRA, the:

jira.exportimport.usesaxparser = true

property will not be set, and so will default to 'false', meaning the old DOM parser is used. This appears to be broken, as trying to import will result in:

Form Errors:

• Failed to import data: Error in action: com.atlassian.jira.action.admin.DataImport@1ee1775, result: error Exception occurred: java.lang.IllegalStateException: Cannot deactivate indexing as it is not currently active.

And a stacktrace in the logs:
