Unable to run search program (9.1 Pro)

When I try to use the Search function of Lifesaver Help (under KDE, SuSE 9.1), I get the uninformative message "Unable to run search program". Searches on Google and the SuSE archives don't yield anything useful. The odd thing is that this is the second SuSE 9.1 system I've installed. This one is an upgrade from 9.0; the other was a fresh install. Help works on the other one but not on this one. Any clues? Paul Abrahams
