This tells me that there is probably a problem with your xauth setup..
Can you actually run *any* X11 commands from that session?

Hmm, that is quite odd, can you try running this from the command line:
python -c "import pygtk;pygtk.require('2.0');\
import gtk;print(gtk.gdk.get_display())"
If that does not work then there is little xpra can do as this means gtk
cannot access your display.
