dash-to-dock from software crash the whole session in Bionic

[Christophe C]

If i install dash-to-dock from the repo in bionic (sudo apt install gnome-shell-extension-dashtodock), the gnome-shell session crash (under xorg or wayland) => return to the connexion screen.

Installation of the extension from https://extensions.gnome.org/ work perfectly.

Others users on the ubuntu french forum have the same problem.

I use that extension since a while now, and have not met instability. so that extension might not be blamed.

For testing purpose, unset all the installed extensions, via tweaks, then logout/in, and set back the extension one by one to find which one is conflicting.

I suppose you have already made some system cleaning using gtkorphan & bleachbit (as root, but select carefully the options).
A week back or so, some users have pointed a possible gjs cause; and we still wait for an upgrade.
Some others also have suggested to not install dash-to-panel and dashtodock together. (myself not using dash-to-panel)

Also joint the crash file to get a chance to identify the cause (or any message logged into journalctl.
