I took the liberty of reporting this upstream with slightly more analysis. The URL is here: https://bugs.freedesktop.org/show_bug.cgi?id=15903 I'll leave it up to the maintainer to tag this "upstream". I don't feel that it's appropriate for me to do it since I'm neither the maintainer nor the original reporter. I hope you will consider including my patch anyway so we don't have to wait for upstream to include it. :-) --Jay
