Bug#791389: gnome-session: "Oh no! Something has gone wrong" when used under x11vnc

[Andrey VI]

Package: gnome-session
Version: 3.16.0-1
Severity: important

Dear Maintainer,

after routine Debian testing updates, restarting and VNC to computer I see "Oh no! Something has gone wrong" screen AND 'abiworld' empty document above it.
I have no direct access to that computer, only SSH and VNC.

May be related lines from /var/log/messages:
