Additional thought on my scenario ... I was also working in a duel monitor mode when gnome crashed. In my case Thunderbird was on my primary monitor, and the thunderbird dialog came up on my secondary monitor. Interacting with this dialog is when gnome crashes.

(Note: I originally thought that if I moved the find window to the other window and then searched, gnome-shell crashed, but I think what happens is a) I open the window, b) I move it, search for something, and it works, c) I close it and re-open it - it then opens on the other monitor and searching will crash gnome-shell.) gnome-shell restarts, but the crash causes data loss, as most of the running applications don't reappear when it restarts. In case it's relevant, I have a laptop screen set at 2048x1152 and an external monitor configured to be above it at 2560x1440.
