Ok, back at that computer now, and yes, I see those messages right
away. In fact, they seem to happen before gnome even starts up, ie I
see those messages long before the first messages from gnome-session:

IOW, it happens already during the graphical boot before I have even
typed in my disk encryption password.
Then it starts again when gnome starts.
I just checked: I have exactly 8192 warnings from the early boot
before the first gnome warning. Which sounds like too round a number
to be an accident.
I will try the patch Alex pointed at next:
https://patchwork.freedesktop.org/patch/594539/
and see if that fixes it for me.
