I have to confess, this is new to me, so I may have gotten something wrong.

first guess would be: make sure you installed with "make install" and you're 
running LyX from your installed path, and that it's using your wrapper in /usr/local/bin.

The AppArmor test is quite straightforward:

  /usr/local/bin/lyxwrap-2.3 touch ~/something
  /usr/local/bin/lyxwrap-2.3 touch /tmp/whatever

check if created

  /usr/local/bin/lyxwrap-2.3 rm ~/something
  /usr/local/bin/lyxwrap-2.3 rm /tmp/whatever

check if removed. Also, this might be useful to troubleshoot:

  dmesg | grep 'DENIED\|apparmor'

(but that's mostly useful when it stops you when you don't expect to be stopped)

        T.
