--- Comment #23 from Rico kgbricola@web.de 2013-02-15 03:43:22 CST --- Which version is this (mesa git commit?).
It looks like http://cgit.freedesktop.org/mesa/mesa/commit/?id=5751d0cb2dd6d1682d2a954e3f0... may solve it?
Could you build mesa with debug symbols? At least you should use "--enable-debug" in configure ...
