Steps to reproduce:

1. Create an arbitrary web content structure (Admin --> Content --> Manage --> Structures).
2. Create a template using this structure (Admin --> Content --> Manage --> Templates).
3. Create a web content with this structure.
4. Change the default language of the portal (Admin --> Control Panel --> Portal Settings --> Display Settings).
5. Export the pages of the portal (I tested with public pages, default settings) (Admin --> Pages --> Export)
6. Delete the web content.
7. Try to import it back with default settings (Admin --> Pages --> Import).

Result: com.liferay.portlet.dynamicdatamapping.TemplateNameException is obtained and importing fails.
