Package: libcogl20 Version: 1.20.0-2 Severity: important Dear Maintainer,
* What led up to the situation? After a dist-upgrade, gnome shell got removed. After gnome-shell became available for installation again, it installs cleanly again, but segfaults when starting. Relevant error messare from /var/log/message: Aug 28 19:32:56 della kernel: [149450.625143] gnome-shell[27088]: segfault at 64 ip 00007f7502408440 sp 00007fff5c4861c8 error 4 in libcogl.so.20.3.0[7f75023b7000+a1000] Aug 28 19:32:56 della gnome-session[26954]: gnome-session[26954]: WARNING: Application 'gnome-shell.desktop' killed by signal 11 Aug 28 19:32:56 della kernel: [149450.793560] gnome-shell[27103]: segfault at 64 ip 00007ff8bea28440 sp 00007ffd76e818c8 error 4 in libcogl.so.20.3.0[7ff8be9d7000+a1000] Aug 28 19:32:56 della gnome-session[26954]: gnome-session[26954]: WARNING: Application 'gnome-shell.desktop' killed by signal 11 Aug 28 19:32:56 della gnome-session[26954]: gnome-session[26954]: WARNING: App 'gnome-shell.desktop' respawning too quickly * What exactly did you do (or not do) that was effective (or ineffective)? I do not know how to prevent gnome-shell from using libcogl in order to make sure that it is indeed a libcogl problem rahter than a gnome-shell roblem. -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.1.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libcogl20 depends on: ii libc6 2.19-19 ii libdrm2 2.4.64-1 ii libegl1-mesa [libegl1-x11] 10.6.4-1 ii libgbm1 10.6.4-1 ii libgdk-pixbuf2.0-0 2.31.5-1 ii libgl1-mesa-glx 10.6.4-1 ii libglib2.0-0 2.44.1-1.1 ii libwayland-client0 1.8.1-1 ii libwayland-egl1-mesa [libwayland-egl1] 10.6.4-1 ii libwayland-server0 1.8.1-1 ii libx11-6 2:1.6.3-1 ii libxcomposite1 1:0.4.4-1 ii libxdamage1 1:1.1.4-2+b1 ii libxext6 2:1.3.3-1 ii libxfixes3 1:5.0.1-2+b2 ii libxrandr2 2:1.5.0-1 Versions of packages libcogl20 recommends: ii libcogl-common 1.20.0-2 Versions of packages libcogl20 suggests: ii libgles2-mesa [libgles2] 10.6.4-1 -- no debconf information
