When working with KDE4 on my system with 865G graphics chipset I experience random crashes of kwin, occuring inside the graphics driver.
They have been reported to KDE as:
https://bugs.kde.org/show_bug.cgi?id=297348
and
https://bugs.kde.org/show_bug.cgi?id=296496
and resolved as: "It crashes right in the driver - nothing we can do about it."

Currently I'm using kernel 3.2.11
mesa driver: 7.11.2-1 (at least during the 297348 crash)
libdrm-intel1: 2.4.32-1  (at least during the 297348 crash)
xserver-xorg-video-intel 2:2.18.0-1  (at least during the 297348 crash)

Grpahics chipset:
00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller])
        Subsystem: Intel Corporation Desktop Board D865GBF
        Flags: bus master, fast devsel, latency 0, IRQ 16
