kwin_gles backtrace logfile

Using kwin_gles instead of kwin causes freeze after entering KDE. This bug is
reproducible not each time when starting kwin_gles by hand but it's
reproducible almost each time when kwin_gles starting automatically with system
booting. This issue appeared since Jan. ~18-20.

kwin developers believe that problem is in driver. Here is bug report:
https://bugs.kde.org/show_bug.cgi?id=313599

While freeze moment turning compositing off gives nothing. But switching from
kwin_gles to kwin from any VT unfreezes desktop.


Software:
Kubuntu 12.10 x86_64
Linux 3.5.0-22
KDE 4.9.5, desktop effects enabled.

Mesa: 2.1 Mesa 9.1-devel (git-148fc6d quantal-oibaf-ppa)
libdrm-radeon1: 2.4.41+git1301220934.303ca3~gd~q
xserver-xorg-video-radeon: 1:7.0.0+git1301160928.102ee4~gd~q
xserver-xorg-core: 2:1.13.0-0ubuntu6.1

Hardware:
Intel C2D 7200

Note. Please se in atachment: kwin_gles backtrace logfile (the same is on
