Having the exact situation as you, only the unhandled exception when submitting (none) values in required fields is only occurring when using cascade dropdowns in calendar lists.
I also still need to user the 'required field' when using the 2014-1 version of spservices.
I'm in Office 365 (SP 2013)
You could use custom JavaScript/jQuery client side validation as an alternative to SharePoint's validation since it's not ideal anyway. Especially when using required lookup columns.
