Bug#797290: libcogl20: gnome-shell segfaults with error 4 in libcogl.so.20.3.0 on intel DRI driver: i965

[Igor Nikolic]

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:

   * 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.
