Larry -

Of course you should never be left without the comforts of the Squeak debugger, but...

If you can get close to the error, you may be able to catch itn by running the last bit of code simulated.  In other words, put a halt as close before it as you can, and the use the debugger step command to execute the part that crashes.  There's a fair chance that the context stepper will complain in a more civilized manner than the VM.

If not, then open a transcript and try
	ContextPart trace: [stuff]
where stuff is where the crash happens (again, try to get close before this -- it's pretty verbose).  The crash may still happen, but the trace in the transcript will tell you where it's dying.

Good luck, and let us know what you find.
