Dear Maintainer,

if I try to open a attachment in thunderbird (e.g. a pdf file), I get errors of
this form

    <viewer>: error while loading shared libraries: <some library>: failed to
map segment from shared object

(It tried out several viewers.)

I solved the situation by adding the line

    /usr/lib/x86_64-linux-gnu/* rm,

to my `/etc/apparmor.d/local/usr.bin.thunderbird`.
