I'm working on an app that uses a qwizard for the main window. This is a 
PerlQt/PerlKDE application. I'm on Qt 3.3.4, Perl 5.8.8, and PerlQt 3.009.b2. 
When I reimplement the help() slot to load khelpcenter I get the following 
error: khelpcenter: ERROR: Communication problem with khelpcenter, it 
probably crashed. The main window code is attached.
