pigment is a framework for doing openGL based UI and there is a python
binding for the pigment library as well. I'm using pigment-python to
load a picture into a gdk pixbuf and then show it on screen in a opengl
viewport. When I do this in EXA using ubuntu package versions the
xserver SEGVs, when I do it in in UXA using ubuntu package versions then
I get a python SEGV instead but the python SEGV stack happens deep
inside the miptree code in i965_dri.so so I think it's an intel mesa
bug.
I've managed to reduce my python app down to a minimal testcase which
can be used to repro this bug (see attchments). In all comments and
attachments below, I will be using post-ubuntu bits like .29 kernel and
intel+libdrm from git but still mesa7.4.
REPRO STEPS:
On intel G45, download the testcase.tgz extract it and run "python main.py"

xserver "bt full" for the SEGV that's triggered in EXA
I will now attach similar logs recorded with the exact same package
versions but in EXA (in this case the xserver hits a SEGV). First off,
here is the backtrace from the xserver:

On top of the versions I used for EXA testing, if I installing mesa git
HEAD as of April 4th 2009, this is what I see:
for UXA, the scenario is fixed (image now loads and renders fine)
for EXA, the xserver does not SEGV anymore but the app is extremely
buggy, hogging CPU, runs in all constant "grayed out unresponsive"
state, shows many rendering defects etc (even when minimized it keeps
blurbing stuff to the screen).
