Hmm, interesting, unfortunately you're right it's not enough information yet, but it does prove this to be a mesa bug rather than -ati. Refiling.

Looking in the code, it seems to be crashing around these lines:

   if (drawable->base.pDraw == NULL)
        return GL_FALSE;

    pScreen = drawable->base.pDraw->pScreen; // <-- crash

Since it had checked that pDraw is not NULL, it makes me wonder if it is a corrupted memory issue. A race condition is another possibility, particularly when in the middle of destroying objects. Unfortunately it looks like a lot of variables have been optimized out. It would be nice to know what is going on with the r300_dri.so calls but I'm not sure that would buy much more info than we know so far.
