I would tip that these aren't HAL errors. I guess this happens if you suspend 
a long time (and I guess you use GNOME and not KDE). After 6 hours suspend 
time the DBus method call times out, which leads to an error message.

I fixed this in KPowersave by stop the time before the suspend, stop the time 
after resumed, calculate the time between suspend and resume and if the time 
is more than 6 hours: show no error message to the user.
