GPG seems broken on FC13 after upgrade.

I don't know about Qt libraries but I found that just running the GTK
code fragment checked it fairly easily:

/* Simple check for X display with GTK+ */
include <gtk/gtk.h>

void main (int argc, char **argv){

gboolean return_code;

/* Checks is X Server responds to initialization 
   Returns true on success, false on failure */
return_code = gtk_init_check(&argc, &argv);

printf("Return Code: %d\n", return_code);


Since I do not code much C anymore, it seemed way too easy of a check
but worked very well.  When I had my DISPLAY set but local X-Server not
running, it returned false but when I ran it with the X-Server running
it correctly displayed true.  It does the same functions as gtk_init but
returns a status code.  

Could this be what is needed here to check to see if curses is called
when the DISPLAY is set but there is no X-Server or permissions are
