Bug#1021187: gnome-keyring: /usr/bin/gnome-keyring-daemon --daemonize --login 100% CPU usage

[Elmar Ludwig]

I am seeing the same issue on my laptop with debian testing (bookworm/sid).

Downgrading all installed packages from src:glib2.0 to version 2.74.0-1 fixes
the issue for me. Since the last update of gnome-keyring was several months
ago and glib2.0 2.74.0-2 migrated to testing on 03 Oct 2022, I suspect some
recent change in glib2.0 triggered this.

I briefly looked a the top frames of the stuck process in gdb and all of them
were in glib2 and glibc. I see randomly (I guess depending on timing) one of
these backtraces:
