CTD on changing frequency

Was flying into KOXB via the RNAV approach for RWY 02 tonight. Potomoc Approach cut me loose to CTAF about 12 miles out from CIRAN. As soon as I switched the frequency, XSB crashed and took X-Plane 10 down with it. I had a CTD while taxiing on the departure in my first attempt to make the flight, so I conveniently had GDB running.

 

The backtrace:

The buffer underruns don't appear to be significant, due it being reported in the GDB output rather consistently throughout the flight. Any thoughts?
