Description Piotr Mierzwinski 2017-01-03 17:58:12 UTC 
I wasn't able to report by drkonqi, because in window to login after putting user and password button "Next" or "Finish" wasn't enabled.
Anyway KUser crashed when I tried to run it. I passed password and after 1 sec. I saw drkonqi window about crash.

Comment 1 Piotr Mierzwinski 2017-01-03 17:59:56 UTC 
To complete info about drkonqi. Also button "Login" wasn't enabled.
Comment 2 Piotr Mierzwinski 2017-01-03 18:04:38 UTC 
I was able reproduce this crash. It happens when I tried to run kuser with root permission. When in konsole I did:
$kuser 
then application just run with message that cannot read /etc/shadow
When I tried
$sudo kuser
then application crashed
I'm not sure is this distribution issue or something with kuser.
Comment 3 Christoph Feck 2017-01-03 18:15:43 UTC 
You need to use kdesu or kdesudo to use KDE applications as root. Alternatively, you can manually setup the required DBus session and environment variables.
Comment 4 Piotr Mierzwinski 2017-01-03 18:21:20 UTC 
Sorry. KUser krashes usig both application. I tested by run it in konsole.

My first try was running kduser using krunner (Alt+F2) and then first window what I saw was kdesu.
Comment 5 Christoph Feck 2017-01-03 18:22:37 UTC 
Please add a backtrace when run with kdesu. It should be different.
Comment 6 Piotr Mierzwinski 2017-01-04 17:56:21 UTC 
Put (in first message) stacktrace comes from running by kdesu (Alt+F2 run kdesu).
I'm not sure how to add debug packages in Arch. I found somwhere in net that there is no provided such packaces, so I would have to just build kuser and install it, breaking coherence of the system :/.
Comment 7 m3johan 2017-02-25 19:07:02 UTC 
I have the exact same error. Does not work with kdesu.
Same backtrace as in first post.
Comment 8 fedeb703 2017-05-31 18:16:58 UTC 
Same here, not able to run Kuser, same backtrace.

What other info can I provide?

kuser no longer exists as a separate thing and hasn't for several years; it's relevant functionality now exists as the Users page in System Settings. If you experience an issue with that page, or want to request a new feature for it, feel free to open a new bugzilla ticket about the matter at https://bugs.kde.org/enter_bug.cgi?product=systemsettings&component=kcm_users.

Thanks folks!
