Ugly workaround from hell :

• Copied MzPaginationModule, pasted it in my app.
• Fixed some imports
• renamed selectors to app-mz-pagination...
• replaced in pagination.component.ts line 20 :

// before
return Math.ceil(this.totalItems / this.itemsPerPage);
// after
return Math.ceil((this.totalItems || 1) / this.itemsPerPage);
