Problem:

• When you export a Template´s graphs only, and edit the file manually to change the "hostname" entry (to use the graphs in another host), and import the full Template again (only the graphs, without any items) the import process should return "FAILED" because the new template does not have any items (and so, cannot create the graphs).

How to re-create the issue:

• Export only the graphs of a Template (no items);
• Edit the file manually and change the "hostname";
• Re-import the Template;
• The host will be created, status "OK" in the Import page but since there are no items Zabbix cannot (correctly) create any graphs.
