Bug#1114797: gdm3 locked up, had to reboot

[Van Snyder]

Package: gdm3
Version: 48.0-2
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where
appropriate ***

   * What led up to the situation?

The KDE New User widget created a user with uid:gid = 1000:1000 in
/etc/passwd*, but set up its home directory with uid:gid = 1001:1001.
When I
tried to log in, gdm3 wouldn't allow even to insert the password, and
wouldn't
return to the "select the account" screen. I had to reboot.

There's a chance there was already a home directory for the new user (I
didn't
reformat /home when I installed Debian 13), but if so the KDM "new
user" widget
didn't look for it and set uid:gid in /etc/passwd to be the same as in
the home
directory. But that's a problem for KDE, not gdm3

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Changed the uid:gid in /etc/passwd to match uid:gid in the home
directory.

   * What was the outcome of this action?

gdm3 no longer locked up.

   * What outcome did you expect instead?

I had expected gdm3 either (1) not to lock up, or (2) to complain about
uid:gid in
/etc/passwd* not matching the home directory, and then (3) to return to
the
"select an account" page.
