Subject: 2.6.30: hald crashes on resume from STR apparently on LED device

I did not experience this crash under 2.6.29. I got it under 2.6.30 
(both rc and final) with varying frequency. At least for me it is 2.6.30 
regression.

hald aborts on D-Bus assertion with stack trace below.Program received 
signal SIGABRT, Aborted.

Appearance of hald-addon-leds may be red herring; still here is the only 
led device I have (for Intel 3946ABG).

udi = '/org/freedesktop/Hal/devices/leds_iwl_phy0_radio'
  info.addons.singleton = {'hald-addon-leds'} (string list)
  info.capabilities = {'leds'} (string list)
  info.category = 'leds'  (string)
  info.interfaces = {'org.freedesktop.Hal.Device.Leds'} (string list)

  info.subsystem = 'leds'  (string)
  info.udi = '/org/freedesktop/Hal/devices/leds_iwl_phy0_radio'  
(string)
  leds.device_name = 'iwl-phy0'  (string)
  leds.function = 'radio'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'leds'  (string)

(string)


 This is Dell XPS M1330 notebook. I am ready to provide any required 
information; so far crash is reproducible after several suspend/resume 
cycles.
