x.org + GTK + Nvidia driver weird interaction?

Hi all, I'm in the process of assembling a LFS/BLFS testing (kernel
18.104.22.168, GCC 3.4.1, NPTL) system (to eventually replace my current LFS
system - kernel 2.6.4, GCC 3.3, Linuxthreads). The LFS portion seems to
work perfectly, but I have a bizarre problem in the "Beyond" portions.
I'm hoping someone here can point me in the right direction so I can
solve the problem.
Essentially, the threefold combination of x.org 6.8.1 plus GTK+ plus the
NVidia binary driver causes X to segfault the moment a GTK+ application
* I installed the newest x.org (X11R6.8.1).
* I installed the newest 6111 NVidia binary driver.
* NO GTK+
I altered my xorg.conf to use "nvidia" instead of "nv", turned on
RenderAccel, and enabled the Composite and Render extensions. I ran X,
everything works fine - opened XClock, XEyes, and XTerm (ran it both
normally and using an Xft Font) - everything works fine, and fast. Ran
X both with xcompmgr and without - also fine, and fast.
Installed PekWM as my window manager (which I also use on my stable
system), and started using it. Also works fine.
So far, so good.
* I installed GTK+ 2.4.9 (in preparation for installing some/most of
Gnome 2.8.0), together with the prereqs of ATK 1.8.0 and Pango 1.6.0.
After installing, I started X again - again, all is well. Then, to test
GTK+, I ran gtk-demo, and... Segfault - together with the video
glitching so bad I had to use Alt-SysRq-S and Alt-SysRq-B to get out of
there. Most of the window came up, though, before the crash - only the
treeview on the side didn't.
Anyway, I've spent several days already bashing this one about. Here's
what I've come up with so far.
* It is definitely the GTK+ treeview that is triggering the problem - I
can run simple GTK apps that don't have it, and they work fine. I
tested a few simple apps with Images, TextViews, splitters, etc., and
everything seems to work fine. I added a treeview to the app, and it
segfaults the moment the treeview is selected.
* It doesn't seem to be related to the theme engine. I've tried the
default engine, as well as Ximian's industrial, and they both exhibit
the same behaviour.
* GTK+ 2.4.1, 2.4.9 and 2.4.13 all exhibit similar behaviour, although
2.4.1 is more stable with my test programs (although not gtk-demo - I
suspect this is because it doesn't try to do anything when you select a
* Nvidia drivers 5336 (with kernel 2.6 patches) and 6111 both exhibit
* The problems go away when I use "nv" instead of "nvidia", although the
drawing in X is abysmally slow - even without a composite manager.
* the xorg log has nothing in it but the normal startup code (which
looks fine to me), and then the signal 11 crash.
So, I guess what I'm asking is does anyone have any ideas as to where I
might go/what I might try from here? Does anyone have the NVidia binary
driver, x.org 6.8.1, and GTK+ 2.4.x working together?
I can gladly send any information requested - xorg.conf, build options,
etc. I would certainly like to compare mine to those from someone's
