It is definitely relevant. The main function in Nautilus had code to setenv
DISPLAY to be DisplayString (GDK_DISPLAY ()), although we just removed that.
I think this may have led to the problem I was seeing in the first place,
although I'm not certain.

This is unfortunate, because gdk_get_display () is now used explicitly both
in libbonoboui and in 4 or 5 places in nautilus. Michael had thought that it
was the function to call to get the canonical form.

Michael, can you follow through on this and make sure it gets fixed?
