Bug Description

There were many programs open as the crash occurs. There were lots of terminal windows, thunderbird, firefox, pidgin, gedit, thunar, nemo, synergy, transmission, solar, nextcloud and GNOME system monitor and maybe more open. Then I was opening a popup window and the shell froze except the mouse cursor which was responsive as always.

After a while the system presents me a fresh gnome login screen. Very annoying...

I saw many segfaults from "Chrome_~dThread ... error 6 in libxul.so" in dmesg afterwards although I did not start any chrome or chromium process.

Sorry, I don't want to work without all of these extensions until the very same crash happens again. Some of them are essential to work flawlessly.

Also I've got a .crash-file here with 180 MB and there is a .uploaded-file beneath so I thought it was already uploaded to launchpad. I called `ubuntu-bug gnome-shell`, then it collected some information and opened launchpad to file the bug. So the new bug ID is the one in the title I guess. I also found all my uploads using my whoopsie-ID and here is the link to the file: https://errors.ubuntu.com/oops/1655e342-234c-11e9-9e6a-fa163ee63de6

Thanks for the link. That is bug 1813853, so the problem seems to be the 'dash-to-panel' extension.
