[Pkg-utopia-maintainers] Bug#510170: this breaks pm-utils too

[Florian Kriener]

This bugs also affects pm-utils (from experimental), because somehow pm-
powersave is called from hal-system-power-set-power-save(-linux). The 
script hal-system-power-set-power-save reads "true" or "false" from 
standard input into $value. However, it always reads "false" on my 
system (KDE4). This breaks pm-powersave, since now "pm-powersave false" 
is called when on battery and on ac power.
