Unknown protocol "help"

5 Apr 2003

      Hello,

I am running SuSE 7.3 prof. with KDE 2.2.2.

Everytime I use the help (KDE-Helpcenter) of for example KMail (Help->Content 
or F1) I get the following error-message-box:

Error
unable to start proccess:
execution of the I/O-module not possible.
klauncher: Unknown protocol "help"

What causes this error? (It ran sometime ago!)
How can I get it working again?

thx
Markus
