gnome-shell in experimental was compiled against gcr from unstable,
so a higher version in dpkg-shlibdeps wouldn't have helped here; and I
don't see any recent source changes that should have prompted a higher
build-dependency.

Not much has changed in gcr between 3.28 and 3.33 at all, although there
are some annotation fixes that might affect gnome-shell. Did you also
upgrade gir1.2-gcr-3, or just libgcr-base-3-1?

Which gcr-related packages did you upgrade in the transaction that
triggered these crashes? For example, did you upgrade gcr or libgcr-ui-3-1
from experimental?

Which version of gnome-keyring did you have when this crash existed?

Presumably you already had gnome-settings-daemon 3.34.x from experimental
in order to satisfy gnome-shell's dependencies?

Are you able to get a backtrace from this crash? (If you install packages
from experimental, I would suggest installing systemd-coredump, or
corekeeper if you don't use systemd, so that you can get post-mortem
backtraces.)

Thanks,
