Seems as if a model has missing or maybe even faulty thruster glows the game will lock up when you press the launch button.  I traced it back to ship_do_thruster_frame() in ship/ship.cpp being the problem.  It seems that if the game is not supposed to display a thruster glow for a ship it will lock up the game.  I fixed it by checking to see if anim_index <= 1 and if so exit the function instead of continuing.  The thing is that craft that crash FS2 Open like this work fine with the original code.

Mantis.  Post a more detailed explanation there and I'm sure one of the coders will commit the fix.
