What steps did you take leading up to the crash? What options did you set when creating a user?

(In reply to David Shea from comment #14)
The crash was triggered by adding the group "users" when creating the new user.

This issue was absent from anaconda-23.19.1-1.fc23 as included in Fedora 23 Beta TC1.

Another user experienced a similar problem:

I added "users" as additional group for the new user.

Proposed as a Freeze Exception for 23-final by Fedora user dshea using the blocker tracking app because:

 There doesn't appear to be anything in the criteria about user creation, but this is pretty severe change in behavior. This crash will affect any install that attempts to add a user to an existing system group, both interactive and kickstart installs.

[anaconda root@localhost tmp]# anaconda --version
anaconda 23.19.3-1

Tested f23/aarch64 instalation. New user added to 'wheel, mock' groups and instalation failed in same way:

System got installed and is in bootable state. Just no user created.

Another user experienced a similar problem:

I created an administrator user and tried to add it to both the wheel and systemd-journal groups.

Another user experienced a similar problem:

This happens when you specify GID in brackets to a group which already exists.
But this brackets should be considered only if group does not exist.

Discussed at 2015-09-28 freeze exception review meeting: https://meetbot-raw.fedoraproject.org/fedora-blocker-review/2015-09-28/f23-blocker-review.2015-09-28-16.01.html . Accepted as a freeze exception issue, this is a noticeable installer bug that can't be fixed with an update, and should be fixable quite safely.

Another user experienced a similar problem:

tried to install fedora23 cinnamon beta on VirtualBox 4.3.26. I have chosed to add user into additional groups: plugdev,netdev,audio,video. And on Creating users this error appeared

Another user experienced a similar problem:

Just ran installer. USB created with dd. Had to boot in low grahics mode, probably because of bumblebee. Still 1920x1080. Partition existed, added extra existing partition at custom mount point. All in all, nothing special.

The fix for this landed after Beta. You should find that it works in Final TC/RC builds, which you can read about on test@ and find at https://dl.fedoraproject.org/pub/alt/stage/ . Thanks for the report!

Thanks @awilliam. Re-ran the installer labelled TC11.
(Had to use basic graphics mode again, which is a different issue.)
Asked again to add user to group "dialout". Issue not reproduced, confirming the "close" status.
Thank you for your attention.
