Bug#1040920: gnome-flashback: Gnome flashback unsets XDG_SESSION_ID

[Nikolaus Rath]

Package: gnome-flashback
Version: 3.46.0-1
Severity: normal


When starting a Gnome Flashback session, the XDG_SESSION_ID environment
variable is not set. This results on applications that rely on logind to
not behave properly.

Debugging this more closely, I found that XDG_SESSION_ID is still
set in ~/.xsession, but seemingly disappears somewhere in this call:

exec gnome-session --systemd --session=gnome-flashback --disable-acceleration-check
