Package: gnome-shell
Version: 3.16.3-2
Followup-For: Bug #690902
I think I'm hitting a variant of this bug. It happens often when the laptop
is on battery power, and rarely when on AC power.
Exempt from syslog on crash

Followed by X restart logging.
The bug seems to be triggered in libc. The call site of the libc function seems
to have been moved to gdbus code.
Since I can reproduce the bug more or less reliably, I can do some printf
debugging. Are there any ideas where to start?
