[Gonçalo Marrafa (goncalo-marrafa)]

This crash happened right after unlocking the screen saver.

[Gonçalo Marrafa (goncalo-marrafa)]

I can (somewhat) reliably reproduce the issue. It happens after I unlock the screen and when I try switching desktops right after that. If I wait a little after unlocking it seems to work fine.

Hope this helps.

It happened to me on 18.04, randomly during normal office working session.
