           Summary: Kwin crashes screensaver exits
           Product: DRI
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: General
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: isaac.gerg at gergltd.com


I am using KDE 4.6 with Kubuntu 10.10.  When the screensaver exists, Kwin seg
faults in the intel driver code.  The crash is reproducible as long as the
screen saver has been on "for over a few minutes" meaning that if the screen
saver comes on right away and then you move the mouse, the crash doesnt happen.
 But, if you wait something like 10 minutes and move the mouse, the crash will
occur.

Details provided below include the debug symbols.  If you need any other
information, please contact me.  Thank you.

Using openGL for my composting type. Using xorg 1.7.5.

Here is the debug dump....
