I know this is not a bug tracker but I found what seems to be just a typo error.
Line 4166 in latest nightly of zp-core/template-functions.php (Revision 6227):
there is a missing `"` after `else echo 'none';?>`
BTW, it would be nice to have the possibility to customize on theme basis the clear search icon, as it happens for the select search fields icon.

I've added the possibility to customize the clear search icon, it seems to work on my test setup. I can give you the new file if needed.
