This is caused by a free attempt on an uninitialized value.  A patch is 
on the way for this.

This value is the "port:listen address" of the guest's graphics device. 
  I've submitted a patchset that allows a user to pass a GraphicsRASD to 
DefineSystem().  You can specify the port and listen address using the 
RASD.

Also, if the guest doesn't have a graphics device, then a 
KVMRedirectionSAP instance will not be returned for that guest.
