@Jamie Thanks, I hadn't thought of purging to try and clean up from issues like this when there's a left over file but on hearing you say it then it seems so obvious!
As I said above I manually removed the file to get apparmor loading (actually three of them in the /etc/apparmor folders) and not seen any errors since. In fact it was only by chance I saw the one that triggered by above report, I doubt the effect would have been serious enough to cause me issues from the little I understand of this package... But again thanks, purging still seems to have removed a few bits and I will definitely remember to try it in any similar situations in the future. ~$ sudo dpkg --purge snapd [sudo] password for dale: (Reading database ... 402920 files and directories currently installed.)
