Newly kpowersave reports the error message "DBUS daemon not running" more and more often. Likewise the Yast2 power management module says it can not connect to DBUS daemon though it is running in root mode. Nevertheless DBUS is running. Even restarting does not help.

>/etc/init.d/dbus status
Checking for service D-BUS daemon                                     running

boot:/home/elm/.mozilla/firefox> /etc/init.d/dbus restart

error: libhal_ctx_init: (null): (null)

> hal-resmgr
ERROR! 10:11:50 hal-resmgr.c:411 main_dbus() - libhal_ctx_init: (null): (null)

As a consequence of this I can not use kpowersave to suspend or to query for the processor speed.
