In the trigger view (Monitoring / Triggers), sorting doesn't work (for example, nothing happens if you click on Severity or Name).

Viewing the html source sent to the browser from tr_status.php reveals that the links required for the sorting to work are wrong. For example, the link associated to the Severity column is "http://www.example.com:80/zabbix/tr_status.php?sid=9ff536ff806f8fb8" (where the fields sort and sortorder are missing in the URL query).

Notes:
1) This applies to Zabbix 1.8.2 (default version in Debian 6), but the bug tracker didn't let me choose that version.
2) Even when this could probably be considered a minor issue (and I've marked it as such), it's certainly quite annoying when you have hundreds of triggers.
