I did some debugging on a radeon machine I have at home. The problem is that
since mesa commit e6a33570, the dri2 egl driver is uncondionally using version
5 of the dri image extension. The flow is to create a dri image with format
none, and later create one or more subimages out of that image with the
appropriate formats. The segfault happens because the createSubImage hook is
not implemented.
