Correction, here is the output:

Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
xprop:  unable to open display ':0'
usage:  xprop [-options ...] [[format [dformat]] atom] ...

where options include:
    -grammar                       print out full grammar for command line
    -display host:dpy              the X server to contact
    -id id                         resource id of window to examine
    -name name                     name of window to examine
    -font name                     name of font to examine
    -remove propname               remove a property
    -set propname value            set a property to a given value
    -root                          examine the root window
    -len n                         display at most n bytes of any property
    -notype                        do not display the type field
    -fs filename                   where to look for formats for properties
    -frame                         don't ignore window manager frames
    -f propname format [dformat]   formats to use for property of given name
    -spy                           examine window properties forever

Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
mythfrontend.real: cannot connect to X server :0

How do I set magic cookies?
