In a shell (existing gnome-terminal or xterm)
	# ulimit -c 100000
   or
	# ulimit -c unlimited

Then invoke gnome-terminal by hand with strace watching it.

	# strace -f -o /tmp/trace-gnome-terminal /usr/bin/gnome-terminal

If you are lucky you have an exception and learn something.
I did this and noted that gnome-terminal attempts to catch 
most interesting signals.

  3744  rt_sigaction(SIGSEGV, {0x2d3770, [], SA_RESTORER,...
  3744  rt_sigaction(SIGABRT, {0x2d3770, [], SA_RESTORER,...
  3744  rt_sigaction(SIGTRAP, {0x2d3770, [], SA_RESTORER,...
  3744  rt_sigaction(SIGFPE, {0x2d3770, [], SA_RESTORER,...
  3744  rt_sigaction(SIGBUS, {0x2d3770, [], SA_RESTORER,...

So next I took a chance and looked for help "/usr/bin/gnome-terminal --help"
"/usr/bin/gnome-terminal --usage" and I noticed these flags that may help.

    --gdk-debug=FLAGS 
    --gtk-debug=FLAGS
    --disable-crash-dialog
    --g-fatal-warnings

With "strace" if you can discover the signal that is being caught
you can build a version that no longer traps that signal.

Perhaps "--disable-crash-dialog" is being remembered for some reason
by your desktop.  I seem to recall a dialog box 100 years ago....
