We don't get the ls output because it terminates to early I think, but it
works fine with:
xfce4-terminal -x touch /tmp/test
for example.
Even with ls:
strace -fe trace=process xfce4-terminal --disable-server -x /bin/ls
execve("/usr/bin/xfce4-terminal", ["xfce4-terminal", "--disable-server", "-x",
"/bin/ls"], [/* 51 vars */]) = 0

So the process is run. Maybe you have issues with stdin/stdout, I'm not sure.
