            Bug ID: 353825
           Summary: Login by x2go in Plasma 5 crashes KCMInit
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: thomi.schmid at gmx.net

Application: kdeinit5 ()

Qt Version: 5.4.2
Operating System: Linux 4.1.6-10-desktop x86_64
Distribution: "openSUSE Leap 42.1 Beta 1 (Malachite) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I am running openSuSE Leap 42.1 Beta1, with Plasma 5 as the default desktop
environment. 
I installed x2go 4.0.5 including the Perl-Basedir-Module. When I try to login
from another system using x2go client (4.0.5), KCMInit always chrashes during
the login and session startup process. Running Plasma5 directly (without x2go)
works OK. 

- Custom settings of the application:
Access is by x2go client: Configured is "KDE" as window manager to start.

- Additional info:
Accessing this box via x2go and using IceWM or MATE as windows manager /
desktop
works OK.
While KCMinit crashes, the login and session start seems to complete. This
assistant was able to start Firefox to let me create a login at KDE bug
reporting.
