[pkg-apparmor] Bug#882048: apparmor should let thunderbird use signatures from files

[Ben Caradoc-Davies]

Package: apparmor
Version: 2.11.1-3
Severity: normal

Dear Maintainer,

when apparmor is enabled, thunderbird signatures from files disappear. For
example, one account uses: "Attach the signature from a file instead":
/home/ben/.signature-ben at transient.nz

If I disable apparmor with "systemctl mask apparmor.service" and reboot,
thunderbird signatures from files work again.

Kind regards,
Ben.
