Bug#765855: flightgear: crashes on Invercargill, New Zealand

[Michael Shigorin]

Looks like I have reproduced this bug on ALT Linux
with OpenSceneGraph-3.2.1-alt1, SimGear-3.2.0-alt1,
FlightGear-3.2.0-alt1, FlightGear-data-3.2.0-alt1;
rebuilding OSG with the patch derived from upstream
commit 49d560f4d9d0641c98df67264b7ace4733c6b9a9
referenced above in comment #31 didn't change that;
rebuilding SG and FG seems to have fixed it for me.

Proof (hopefully moves to http://fly.osdn.org.ua/~mike/iso/fgfs/):
http://fly.osdn.org.ua/~mike/iso/tmp/live-flightgear-20141101-x86_64.iso

Thanks for the pointer, Rebecca.
