[pkg-fgfs-crew] Bug#797936: Bug#797936: flightgear: Crash on startup: symbol lookup error

[Rebecca N. Palmer]

Control: severity -1 grave
Control: reassign -1 libsimgearscene3.4.0

Confirmed in pure sid (original reporter was using a sid+stretch mix), 
makes flightgear totally nonfunctional.

It looks vaguely like a gcc5 transition issue (the symbol in question 
involves std::string, 
http://sources.debian.net/src/openscenegraph/3.2.1-7/OpenSceneGraph/src/osgDB/Callbacks.cpp/?hl=37#L37 
), which suggests that just recompiling simgear+flightgear (i.e. 
#797944) may fix it, but I haven't had time to actually try that.
