If this happens again, please try to obtain a backtrace from the
locked-up gnome-shell process. I’m not sure it’s enough because the
deadlock could be in the JS code, but that would be a good start.

So this is phatch crashing.

This looks like an unrelated problem with gnome-keyring, but if it
happens right at the same time it might be it.
