Hello,

    Today I updated Thunderbird to version 1:60.0-3~deb amd64 from
pkgmaster.devuan.org/merged ascii-security/main.  And I found myself
impacted from this Debian bug concerning AppArmor:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=887973


  I'm just letting you know I could solve it adding this line to the
Thunderbird AppArmor profile, that is to the file
/etc/apparmor.d/usr.bin.thunderbird:

owner /run/shm/org.chromium.* rw,


  I added it right after the line reading:


  owner /dev/shm/org.chromium.* rw, # for Chromium IPC

/dev/shm is a sym-link to /run/shm.

  The fix that is prioposed in Debian bug #887973 did not solve the
issue to me:

  After editing the usr.bin.thunderbird file I also had to run the
following command as root:


apparmor_parser --replace /etc/apparmor.d/usr.bin.thunderbird


  Hope it helps someone else.
