Package: thunderbird Version: 1:60.0-3~deb9u1 Severity: important At thunderbird startup, I get a completely blank display, associated with terminal message: [GFX1-]: Failed to lock new back buffer.
(I presume this bug should be grave, but how can I be the only person on the planet affected by it? The package is completely unusable to me as of the update.) At each focus event thereafter, the window flashes, and a system log message is output: Oct 15 12:06:27 weinberg kernel: [233610.647925] audit: type=1400 audit(1539565587.008:2707): apparmor="DENIED" operation="mknod" profile="thunderbird" name="/run/shm/org.chromium.viOLay" pid=20087 comm="thunderbird" requested_mask="c" denied_mask="c" fsuid=2983 ouid=2983 (different /run/shm/ tmp dir everytime) Stale apparmor profile affecting latest security update? Looks like #887973 but that was claimed to have been fixed in a version far far away. /etc/apparmor.d/usr.bin.thunderbird, provided by this version of thunderbird, still references only /dev/shm: owner /dev/shm/org.chromium.* rw, # for Chromium IPC I note also this report: https://lists.dyne.org/lurker/message/20180918.101827.26f69559.de.html But users shouldn't be updating /etc/apparmor.d files that are the responsibility of the package. -- System Information: Debian Release: 9.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable'), (5, 'testing'), (1, 'experimental'), (1, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 4.18.0-0.bpo.1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8), LANGUAGE=en_AU:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages thunderbird depends on: ii debianutils 4.8.1.1 ii fontconfig 2.11.0-6.7+b1 ii libatk1.0-0 2.28.1-1~bpo9+1 ii libc6 2.24-11+deb9u3 ii libcairo-gobject2 1.14.8-1 ii libcairo2 1.14.8-1 ii libdbus-1-3 1.10.26-0+deb9u1 ii libdbus-glib-1-2 0.108-2 ii libevent-2.0-5 2.0.21-stable-3 ii libffi6 3.2.1-6 ii libfontconfig1 2.13.0-5 ii libfreetype6 2.6.3-3.2 ii libgcc1 1:6.3.0-18+deb9u1 ii libgdk-pixbuf2.0-0 2.36.5-2+deb9u2 ii libglib2.0-0 2.50.3-2 ii libgtk-3-0 3.22.11-1 ii libgtk2.0-0 2.24.31-2 ii libjsoncpp1 1.7.4-3 ii libpango-1.0-0 1.40.5-1 ii libpangocairo-1.0-0 1.40.5-1 ii libpangoft2-1.0-0 1.40.5-1 ii libstartup-notification0 0.12-4+b2 ii libstdc++6 6.3.0-18+deb9u1 ii libvpx4 1.6.1-3+deb9u1 ii libx11-6 2:1.6.4-3 ii libx11-xcb1 2:1.6.4-3 ii libxcb-shm0 1.12-1 ii libxcb1 1.12-1 ii libxext6 2:1.3.3-1+b2 ii libxrender1 1:0.9.10-1 ii libxt6 1:1.1.5-1 ii psmisc 22.21-2.1+b2 ii x11-utils 7.7+3+b1 ii zlib1g 1:1.2.8.dfsg-5 Versions of packages thunderbird recommends: ii hunspell-en-au [hunspell-dictionary] 1:5.2.5-1 ii hunspell-en-gb [hunspell-dictionary] 1:5.2.5-1 ii lightning 1:60.0-3~deb9u1 Versions of packages thunderbird suggests: ii apparmor 2.11.0-3+deb9u2 ii fonts-lyx 2.3.1-2-1~bpo9+1 ii libgssapi-krb5-2 1.15-1+deb9u1 -- no debconf information -- Tim Connors
