It's TightVNC 1.2.6.
Here's the relevant section of selection.c:
291: static Boolean
292: ConvertSelection(Widget w, Atom* selection, Atom* target, Atom*
type,
293: XtPointer* value, unsigned long* length, int *
format)
294: {
295:
296: if (*target == XA_STRING) {
297: *type = XA_STRING;
298: *length = strlen(serverCutText);
299: *value = (XtPointer)XtMalloc(*length);
300: memcpy((char*)*value, serverCutText, *length);
301: *format = 8;
302: return True;
303: }
So it looks like it's dying doing a strlen of serverCutText? Hm...

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.

I upgraded to 2.3.2.1 on my dual-display Macbook pro at 10.5.6
over the weekend. I've returned to work after the break, and have
had 3 X11 vncviewer app crashes today with a "bus error." This
had never happened with 2.3.1.
Ideas for further debug?
Could you please send me the stack trace of the crash
