Changing the last line of
/usr/share/xfce4/helpers/xfce4-terminal.desktop
to
X-XFCE-CommandsWithParameter=%B -H -x %s;
is at least a workaround for this bug; now the opened terminal window is hold open even after the command has been run and returned. However, with this modification you will always need to explicitly close the window after you are done.
