Binary search is your friend:

- - Is it only one of the ZPTs which cause the crash?

- - Can you trim out parts of its content and make it not crash?

- - etc.

Also, you might try exporting to XML and looking at the XML file for
oddities (mojibake, etc.)

You might try to open the imported folder under 'zopectl debug' and see
if you can examine the contents of the ZPTs.  If that works, then the
issue must be in how 'manage_main' is trying to render the links /
titles of the templates.
