gnome desktop session segfaulted

[Thomas Mayer]

My gnome desktop session just segfaulted or somehow crashed. Before the crash, the desktop session was running for hours, it even survived several s2ram's during the past days.

I did not have these issues for a long time.

My syslog shows up a lot of errors around the crash, not sure which one actually is responsible for the crash.

Something I noticed is that my bluetooth headset got disconnected for no reason a few seconds before the crash. And a few seconds before the bluetooth headset got disconnected, a youtube live video (rather audio than video) ended expectedly.

Attached is an excerpt of my syslog which should contain the relevant period of time.

unattended upgrades did an upgrade this morning:

libgdm1

That could be the reason for this issue. Eventually, a restart of the display manager would have avoided this issue after the update.

I'll track this issue for some time and see if it reappears after a reboot and in regular execution (without update behind the scenes).
