Bug#972716: gnome-shell bombards the log to, being unresponsive and filling up multi-GBs of disk space

[Thomas Viehmann]

Package: gnome-shell
Severity: important

Hi,

Debian gnome-shell seems to also suffer from
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2467

reverting the commit singled out as the culprit in the bug log seems to 
fix things for me.
I've selected a "Gnome on Xorg" session in GDM rather than using the 
default, quite possibly, this was necessary to trigger the problem.
To give you a taste for the severity, note that the below shows up to 
21552 identical error messages being logged in a single second (per the 
timestamp). I had filled up gigabytes of log in no time at all.

Personally, this make things totally unusable for me, but I've not put 
severity at serious because I forgot the exact definition.

Best regards

Thomas
