Thank you for taking the time to report this bug and help to improve Ubuntu.
In testing here, I find that shutting off acpid *completely* gives the same behavior. So this is not a flaw in acpi-support alone, because acpi-support isn't handling this event. Combined with bug #397698, this looks very much like a kernel issue.
