Bug#930800: gdm3: Can't switch user

Package: gdm3
Version: 3.22.3-3+deb9u2
Severity: normal

Dear Maintainer,

I can't switch user by clicking switch user option present in status menu. A
window is opened and asking for password of same user from which I want to
switch instead of opening list users (which happens normally). And when I
clicked on "Login as another user" it pop-up a lock screen. This is not a
consistent bug means I can't reproduce it whenever I want to and resolved by
rebooting the system. I've switched user many time in same session before
facing this issue and this is happening fourth or fifth times in last 3 weeks.
