It probably helps if you could get the stack trace to this message
(printed from function xgetpwuid_self). I haven't checked if my
personal laptop has docker to reproduce this.. In general we won't ask
passwd if the user specifies name/email in the config file. But I
still don't see why git-clone needs that info in the first place.
