I can also reproduce this by running bin/people profileimage --all:
```
phabricator@codereview:~/g/phabricator$ bin/people profileimage --all
Default profile image "v1" already set for "kberry".
Default profile image "v1" already set for "dkatten".
Default profile image "v1" already set for "bougyman".

This is a copy of an instance that was running code from 2015-12. I resolved all Setup issues after upgrade. NGINX is fronting php5-fpm to run the application.
Example backtrace from the stderr output of PHP (via nginx error.log) looks similar to the backtrace above:
