What was the value of host_id? I am assuming it was not an integer.

Okay, it was ugly, but I have resolved this one. Please pull the latest graphs.php from branch 1.2.x and give it a shot.

[broxio]

I had pull from 1.2.x and it resolved the issue.

You can wait for 1.2.7 released this weekend, or download the branch 1.2.x right now. Either way, it'll be fixed real soon.
