[Xquartz-dev] Problems with X11 2.3.2.1

[Jeremy Huddleston]

Which version of vnc is this?  I can take a look at line 298 of  
selection.c to see what it's doing.  My guess, however, is that it's a  
bug in vnc that is triggered by the new clipboard support.  It looks  
like it's crashing while reading the X11 clipboard or primary selection.
