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

[Andrey Borzenkov]

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).

  leds.device_name = 'iwl-phy0'  (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.
