            Bug ID: 307023
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: KDE 4.9.1 crash on login via x2go
    Classification: Unclassified
                OS: Linux
          Reporter: asala at isa.upv.es
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: kded
           Product: kdelibs

Application: kded4 ($Id$)
KDE Platform Version: 4.9.1
Qt Version: 4.8.2
Operating System: Linux 3.2.0-30-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was logging in via x2go and I got this crash. I am not too knowledgeable on
the internals of kde or x2go... this might be an x2go bug... or a kde one
trying to load nvidia drivers when it shouldn't if the display is remote.

-- Backtrace:
