Public bug reported:
TO REPRODUCE:
I attempt to open a URL from a PDF document in Evince.
EXPECTED:
The browser opens the URL.
OBSERVED:
I'm shown an error message:
Unable to open external link
Failed to execute child process “/usr/bin/google-chrome-unstable” (Permission
denied)
journalctl shows:
Nov 06 19:19:18 khaeru-laptop audit[22110]: AVC apparmor="DENIED"
operation="exec" profile="/usr/bin/evince"
name="/opt/google/chrome-unstable/google-chrome-unstable" pid=22110

EXTRA INFORMATION:
- As the messages imply, I'm using Google Chrome "unstable".
- The file
/usr/bin/google-chrome-unstable
…is symlinked to:
/opt/google/chrome-unstable/google-chrome-unstable
- I note that previous bugs, eg. bug #964510, resulted in lines being added to
/etc/apparmor.d/abstractions/ubuntu-helpers that refer to paths in
/opt/google/chrome/. This directory does not exist on my system.
