Repeated property-changed signals

[Richard Hughes]

With git I'm getting the following when I remove AC:

15:56:02.865: acpi_ACAD property ac_adapter.present = false
15:56:03.041: acpi_ACAD property ac_adapter.present = false
15:56:03.048: acpi_BAT1 property battery.charge_level.percentage = 96 (0x60)
15:56:03.051: acpi_BAT1 property battery.charge_level.percentage = 96 (0x60)

acpi_listen seems to think that there is one event from either device,
so I'm unsure what the problem is here.

As a side note, I'm also getting:

!  full path is

With ConsoleKit from git also.
