Zabbix web interface, error when updating host configuration.

[Erik Pihl Østlyngen]

This bug appears in zabbix version 2.4.7 which is currently included in Ubuntu16.04. The problem occurs if I try to update a host, e.g adding an ip address to it. With debug trace activated, I get the following error message:

Incorrect arguments passed to function. [hosts.php:518 → CApiWrapper->__call() → CFrontendApiWrapper->callMethod() → CApiWrapper->callMethod() → CFrontendApiWrapper->callClientMethod() → CLocalApiClient->callMethod() → CHost->update() → CHost->massUpdate() → CHostInterface->replaceHostInterfaces() → CHostInterface->checkInput() → CApiService::exception() in /usr/share/zabbix/include/classes/api/services/CHostInterface.php:259]

The problem seems to have been corrected upstream in version 2.4.8 and is recorded as a major bug:
https://support.zabbix.com/browse/ZBX-9784

After I applied the patch mentioned in ZBX-9784 (r58205), the problem seems to be gone.
