I have discovered the problem.  The Getting Started document is incorrect.  Quoting:

--- BEGIN QUOTE ---

5.7. Open Source BDM Devices

Open Source BDM (OSBDM) devices are supported. The OSBDM device type partitions the device-url as follows:
The number indicates the number of the OSBDM interface to connect to, counting from zero upwards. If the number is omitted, the default is to connect to the zeroth interface, which works well if you have only one OSBDM device connected to your computer.

--- END QUOTE ---

I had to specify 0 explicitly.  I was previously invoke sprite as 

$ m68k-elf-sprite osbdm: twr-mcf51cn

which segfaults.

whereas

$ m68k-elf-sprite osbdm://0 twr-mcf51cn

works.

Looks like perhaps a null-pointer was used somewhere when parsing the command line.  At any rate, I think you'll agree that's a bug.
