gnome-shell crashed with SIGSEGV in _cogl_pipeline_set_parent()

[Martin-Éric Racine]

As of today, gnome-shell no longer launches correctly in Precise. The menu bar fails to appear and the window manager crashes. Rebooting did not fix the issue.

This is fixed in gnome-shell 3.3.90-0ubuntu1 which you should be getting in your updates shortly. Next time I need to remember to add a breaks to the control file so it's more obvious that upgrading could break gnome-shell.

[Alex Rybicki (alex-rybicki)]

I currently have gnome-shell 3.3.90-0ubuntu1installed from the update recently, and am now unable to render gnome-shell as described in post 1. I am unable to determine if this is the package which causes gnome-shell to fail to load, however the symptoms are as described, and have appeared for me within the last update period.
