I have installed XFCE terminal 0.4.5 (via MacPorts) and the text is invisible, the window only contains the background color.
I am using the Quartz port of GTK (instead of X11) so this is probably caused by that.

Here is the console output:
(terminal:77128): exo-CRITICAL **: exo_xsession_client_new_with_group: assertion 'GDK_IS_WINDOW (leader)' failed

(terminal:77128): GLib-GObject-WARNING **: invalid (NULL) pointer instance

(terminal:77128): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed
