I thought the relative dearth of critical bug reports so far was too
good to be true :-)

Sounds like I have introduced a bug into `pwd_mkdb -u', which is the
common denominator in your reports.  `passwd', `chsh', `pw' all use
`pwd_mkdb -u', whereas vipw uses plain `pwd_mkdb'.

I will look at it closely today!

Meanwhile, if this happens to you, just run `vipw' or `pwd_mkdb' to
rebuild your database.
