You are right, sorry. I rebooted the machine because gnome got stuck, got a "do you want to send crash info", and thought that another crash occurred after reboot, but actually it was before reboot.
While checking logs of current boot I saw a line that I don't understand: Mar 14 19:19:16 gnome-shell[2140]: Extension ubuntu-d...@ubuntu.com already installed in /usr/share/gnome-shell/extensions/ubuntu-d...@ubuntu.com. /usr/share/gnome-shell/extensions/ubuntu-d...@ubuntu.com will not be loaded Is it expected? The same is written about all other system plugins. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2056506 Title: ubuntu-dock 89 crashes on gnome-shell 45 with signal 6 when right clicking on the dock [clutter_actor_dispose: assertion failed: (priv->parent == NULL)] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/2056506/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
