I've reverted to gnome-shell-3.24.1-1.fc26.x86_64 to see if the crashes persist. Perhaps this should be a release blocker.
*** Bug 1455851 has been marked as a duplicate of this bug. ***
Probably a duplicate of bug #1451914, which is a release blocker.
I haven't seen this bug any more. If that's true for you too, can you please close it as a duplicate of bug #1451914?
I've moved on to f27 - and I don't remember what triggered this bug - or if it ocured again. Closing per above comment
