Since 4.5.1 I have not been able to create a template that can successfully create a portal from.  I was just updated to 4.5.3 and I still get this:

What's up?

Error parsing Portal TemplateViolation of UNIQUE KEY constraint 'IX_ModulePermission'. Cannot insert duplicate key in object 'dbo.ModulePermission'.
