After much trial and many unanswered questions, I have a patch to make 
KDE3 work on FreeBSD:

The reason things quit working is because nothing could communicate to the 
dcop server correctly.  When ICE bound the listening socket in 
/tmp/.ICE-unix, the last char of the filename got chopped off (because the 
len parameters in the sockaddr and sockaddr_un's were all wrong).  Now, 
the thing *I* would like to know is this: why the hell did this work on 
other systems?
