Interesting.  This may be the first example of someone using XFCE and 
the GUI.  Could you please try the following?  In the source tree, look 
for the file ./libinterp/interpfcn/sighandlers.cc.  Edit that file by 
commenting out the following line somewhere around Lines 472-474 
(sighandlers.cc)

#ifdef SIGCHLD
// octave_set_signal_handler (SIGCHLD, sigchld_handler);
#endif

and recompile.  Let us know how that goes.  Since Qt tries to use native 
resources, this will test whether XFCE is using child processes to some 
extent.
