Looking back at your initial report, it has this telling line about the crash:

Thread 1 "TimberNav" received signal SIGSEGV, Segmentation fault.
-[MapView drawRect:] (self=0xb7ca746e <-[NSView 
displayRectIgnoringOpacity:inContext:]+318>,
    _cmd=0x8a704b8, rect=...) at MapView.m:168
168           NSLog(@"routeVisible: %d", _routeVisible);
(gdb)

The self parameter in the call is a pointer into the code area of the program. 
So it looks like a serious memory management issue in your program where the 
MapView object that you intended to call the drawRect: method on has been 
released already and its memory been overwritten by some other code.

Perhaps adding NSZombieEnabled=YES to the environment before running your 
program might already give you a clue.
