Hello again :)

Built it (Mesa) from source. 7.9.0 it seems. KWin runs! But then.. all I  
get is this:

KWin KCM -> Enable Desktop Effects -> OpenGL -> Apply -> Accept  
Configuration Dialog -> OK -> (hit Accept configuration) -> this:

crash and no effects.

Otherwise works.

Interesting thing is, that the *very* same crash appeared when I tried to  
launch KWin-GLES against NVIDIA binary (forgot to rmmod it and reload X  
server, well, I'm like this at nights =P). On the very KDE desktop start  
it crashed and gave me the very same backtrace. Interesting, isn't it?

Mesa 7.9.0 (Source, installed in home directory along with the rest of KDE  
using the awesome bash=profile script from Techbase and cmakekde (for KDE)  
and Autotools with --prefix=/custom/prefix/ for Mesa)
nouveau from F14 stock, no soirce building here
KDE from source
Kwin-GLES latest checkout from your repo
Qt 4.7.something (must be) Fedora repos stock
F14 stock
and 8800GTS 320 Mb

That's all my system, the relevant part of it.

I'm free now to test it again and again, I hope. So feel free to ask me ;)

Regards,
Ignat Semenov

P.S. Subscribed to the list now, so no need to cross-post to Plasma, if  
any.
