Comment # 6 on bug 1179003 from Dominique Leuenberger

Seems to be mostly a UI-glitch: if going back to the 'main view' and entering
the login keyring again, it is correctly unlocked (but the lock icon on the
main view keeps on showing locked)

With GNOME 40.beta I seem not able to reproduce this issue, which seems to
imply that it got fixed there already.
