Hi, thanks for looking into this! Here is the output you requested. I
specifically waited for the bug to trigger again so I could catch the exact
output when it happens.

Here is all the output:

Thanks for the bug report. The logs indicate this is related to bug 481808, but
a worse manifestation

Please can you run the following:

❯ QT_LOGGING_RULES=kscreenlocker_greet.debug=true
/opt/kde6/lib/libexec/kscreenlocker_greet --testing
and  reproduce the issue.

Also can you share /etc/pam.d/kde  (they differ per distro)

and output of `faillock --user $USER`

Thanks
