Unless, of course your master.passwd file was damaged. But the *.db
files are really just caches for faster access to user data. The
real master file is master.passwd.
The ch* tools typically just change master.passwd, and then call
pwd_mkdb to rebuild the *.db files.
The pwd.db file from before the snapshot only has three entries. From
after, it has four, and one of them has the wrong shell. So it does
seem that chsh is corrupting the file. And fortunately the problem is
repeatable. Any ideas about how to debug it?

P.S. I failed to mention earlier that this is happening on
12.0-RELEASE-p10
I run in to something similar from time to time from about 10.x or 8.x
(i skipped 9.x)
I do not remember exactly what command did the corruption, if it was
vipw or chsh or something else to manipulate user database. The fix was
easy - run it again or use pwd_mkdb
I searched our archive of issues and found it. It was error with "pw"
command which sometimes failed in very weird way:
# pw useradd -n user1 -u 1003 -G wheel -s /bin/tcsh -m -M 0700 -c "User One"
pw: user 'user1' disappeared during update
It was on FreeBSD 8.x. So it is different error than yours.
