DCOPClient::attachInternal ICE Connection rejected! Problem starting KDE on cygwin after updating installation with setup.exe

Hi,

I've been running KDE on cygwin.  Just recently
performed a general update 
with the cygwin's setup.exe automated
installation/update wizard, and now 
after doing it, KDE does not start anymore.

The following message is being printed to the console
in an endless loop 
(until I press Ctrl-C):

DCOPClient::attachInternal. Attach failed
Authentication Rejected, reason : 
None of the authentication protocols specified are
supported and host-based 
authentication failed
ICE Connection rejected!


I'd like to check if anyone else has experienced this
problem, and if anyone 
has a recommendation for a solution, or a good place
to check for what may 
be causing this.  Please let me know if any additional
information would be 
useful.

Thanks,
Marat
