Bug Description

https://errors.ubuntu.com/problem/2bee46d654bf98b7f32986cb50b0688c07eb4f45

---

This happened after I entered the password to unlock the screensaver (note that this was not after a suspend/resume cycle). The unlock screen froze for some time (after displaying asterisks to represent some of the password), then went black, then came back (displaying more asterisks this time), then went black, then gnome-shell crashed and burned and I found this in /var/crash when I logged back in.
