           Summary: systemsettings: Display settings program crashes with
                    screen rotated
           Product: systemsettings
           Version: unspecified
          Platform: Mandriva RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: bil_efff at yahoo.com

Version:            (using KDE 4.2.0)
Compiler:          gcc-4.3.2-3mnb2 
OS:                Linux
Installed from:    Mandriva RPMs

Using an Nvidia graphics card with the nvidia driver and screen rotation
enabled (RandrRotation), I had tried to rotate the screen using the
systemsettings Display program. The program allowed for upside down rotation
but not left and right.  I then change my X configuration to rotate "Left" by
default.  After resetting X, I logged in and ran the KDE
systemsettings->Display program.  The Display program crashed before it ever
opened.

How to reproduce:
Set Xorg settings to those below.  Restart X. Login.  Open systemsettings and
click on Display.

Expected behavior: 
Display shouldn't crash.  At the least, it should open with the option of not
rotating.  

Relevant Xorg:
Section "Device"
    Identifier "device1"
    VendorName "nVidia Corporation"
    BoardName "NVIDIA GeForce FX series"
    Driver "nvidia"
    Option "DPMS"
    Option "TwinViewOrientation" "Clone"
    Option "TwinView"
    Option "AddARGBGLXVisuals"
    # Options to Rotate
    Option "RandRRotation"
    Option "Rotate" "Left" 
EndSection

Backtrace (maybe not valid):

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents
creation of proper backtraces, or the stack frame was seriously corrupted in
the crash.
