ubuntu-bug -w then click on xeyes fails to report a bug

To reproduce run xeyes then run ubuntu-bug -w and close the popup telling you to click on a window. Then click on xeyes. I get an error message from apport saying xprop failed to determine the process id of the window.

Description: Ubuntu 16.04 LTS
Release: 16.04

xprop seemingly gives a lot of output from xprop but this fails when trying to report a bug on it from apport. Instead I get xprop failed to get the process id from the window and this output seems to succeed when I just run xprop on xeyes and get this output from xprop.
the output from xprop on xeyes is.
