I reported a crash to the idSoftware folks that appears to be a Fedora x86_64 specific libGL crash. I'm not really able to provide much in the way of debugging traces other than show that a crash is occuring in libGL. According to id, x86_64 Fedora is the only distro reporting this crash: Core was generated by `./etqw.x86 +set developer 1 +set logfile 1'.
