Comment 53 for bug 446632

There is a proposed patch upstream for those on r2xx graphics cards (9000, 9200, etc.) I have built mesa with this patch in my PPA (https://launchpad.net/~gomyhr/+archive/standard/). The easiest way is probably to add the PPA to /etc/apt/sources.list, since the source package mesa builds several binary packages, and you would want to upgrade all, but not install any that you don't already have. (Alternatively, you may download all the binary packages for your architecture to a folder and `dpkg -i -O *.deb`).

It would be nice if those of you who have r2xx chipsets could test the build and see if it fixes the problem (and if it doesn't maybe get a new backtrace, since it may be a different issue masked by the first one).
