Problem with dcopserver

  Dear All,
        I have been trying to use Gwenview with a knoppix distribution 
running fvwm. It seemed to work to begin with, but now gives an error

 There was an error setting up inter-process communications for KDE. The 
message returned by the system was:

Authentication Rejected, reason: none of the authentication protocols 
specified are supported and host-based authentication failed

Please check that the "dcopserver" program is running!

gwenview then starts up but is very unstable and crashes, often wehn 
changing directory with a similar error to above.

 I have gwenview recently installed on another Knoppix system (apt-get) 
which is more stable. Is there anyway of switching the inter-processing 
system off, or is there a known thing I may have done to start causing this 
error.

  Many thanks for any help

  regards
