Hi Jason Well, I tried once with the nvidia-drivers as well and I got a segfault in libGL instead, but I will try again.
This was on a Gentoo Linux, not on a Fedora, but the versions of nouveau-drivers, mesa, qt and openscenegraph were basically the same. While I could reproduce it on Fedora 16, it works on Kubuntu 11.10 as Robert said. The version of Qt is always 4.7.4, so it may be the nouveau-drivers and the failure I had with the nvidia-drivers was something different, but I will check again. Interestingly, openscenegraph is currently the only 3D-library having a problem here, the demos from Visualization Library with Qt work.
