The following patch mitigates the error message, but it's only a partial fix for the issue (which is white tabs). Note that I had python 3.5 installed whereas the apparmor profile only supported 3.0-3.4.
So there's something else to do, and it also seems to be related to apparmor (because when disabling the profile tabs are rendered correctly).
