Kpowersaved no longer suspends to disk or to ram ...

Hi !
Until today, i’ve used Kpowersaved for suspending my laptop to ram or to disk, it always worked perfectly

but since today, and i really don’t know why, kpowersaved’s suspend features no longer works, kpowersaved just crashes when i ask him to suspend

i am forced to “killall” it and to start it again, but suspending still doesn’t work, then i restart it as root, and it works !!!

it is obviously a permission-related bug, but i did not modify anything on my system … excepting updating my system through yast …

is there any cleaner way to solve this than chmoding the executables ???
