[.805][CTD] CTD while exploring world map

I have had this CTD many times (six-ish)  now and it always seems to be caused by the same activity.  When I am fairly zoomed in to the world map and using the left click & drag to move the map around.  "Throwing" the map, or trying to move it too quickly, cause one stutter in all the sound, then the game hangs for about a second, then CTD.  

Here is the debug.err for a second crash with the same circumstances.

Here is the memory dump for that crash

Saw frogboy talking about lowering resolution in the B3 change log so I tried that too.  It is always during map movement.

Having a blast otherwise.  Hope these help.
