I'm experiencing a similar (or the same) bug. I'm running a fresh install of pure Xubuntu 12.10. Suspend works perfectly on battery. When I close the lid and disconnect AC power (either by pulling the adapter or undocking), the laptop doesn't suspend.
When I open the lid again, I see the XScreenSaver lock screen. I may have had XFCE set to lock the screen when the lid is closed on AC; I'll double-check.
