Sorry, my mistake, there was a clear test case. Still crashes with Qt
5.3.2 in vivid when using xvfb-run. Works with normal qmlscene without
xfvb-run.

It even crashes with QT_QPA_PLATFORM=minimal xvfb-run -a qmlscene
/usr/share/ubuntu-html5-container/examples/simple/simple.qml - but it
gives more debug output. It seems to be because of
createPlatformOpenGLContext is tried to be called.

Qt 5's Qt Quick 2 / QML2 requires OpenGL (2.0+) support but probably
this should fail more graciously. I don't think this is a high priority
bug though. It might be good to think of a good test case / explanation
and report to upstream https://bugreports.qt-project.org/.

xvfb-run is successfully used to run Qt unit tests.
