Bug#798412: [pkg-fgfs-crew] Bug#798412: flightgear: fgfs always segfaults on exit

[Rebecca N. Palmer]

This is probably the bug fixed upstream (from 3.5) by 
http://sourceforge.net/p/flightgear/flightgear/ci/033957003f4be52ea554a4260b70f1f97440dca0/ 
, which occurs after settings are saved and is hence a harmless annoyance.

(Note that 3.5+ also enable the launcher by default, which causes a 
different crash on exit, but that one is also harmless.)
