A simple app that just shows a Stage and a Rectangle will segfault when attempting either a Stage.close() or FX.exit() to quit the app, and we get the standard "Report problem to Apple" dialog, stating the problem may have been caused by libnewt.jnilib.

I've attached an example test case, as well as the contents of the Report from the OS X error dialog.

This interferes with automated performance testing.

The console output is:
