If trigger2 linked with trigger1 in one template T1, host "test_host1" linked with template1 (in the frontend we see that T1.Trigger2 depends on T1.Trigger1), then export host. In the zabbix_export.xml file we see the following dependencies:

• <dependencies>
• <dependency description="test_host1:T1.Trigger2">
  <depends>Template1:T1.Trigger1</depends>
  </dependency>
  </dependencies>

In this case dependency is not correct, there should be host "test_host1:T1.Trigger1" but not the "Template1".
Please see attached screenshot for details.
Has been checked in the Zabbix v1.6.3.
