Comment 1 for bug 797996

I can confirm the bug reported by eugenio. Same or very similar symptom here, running Ubuntu 11.10 64-bit with Unity on Samsung R710 notebook (only runs Oneiric with acpi=off boot option btw.) - The indicator just doesn't start but reports an error. Please see below.

Thanks in advance for looking into this.
