I get the same error. Some more notes:

By a combination of kills and breaks (a final break seems  
necessary...?) I was able to kill the evaluation. When I switched the  
language to Pretty Big, I got a "read found code compiled for 4.2.1.6,  
wanted 4.2.1.7" (paraphrased because it is no longer in front of me).  
I have no idea what code in particular it's taking about.

My conjecture is that Robby's commit (r15795) is responsible for the  
error message that actually gets shown ('locate-frame' occurs nowhere  
else in the collects, as far as I can tell), but there seems to be an  
underlying problem. That is, there's an error reporting the real error.

I had run a full setup-plt immediately before starting DrScheme, so  
somewhere code is not getting recompiled. I'm currently in the middle  
of a "setup-plt -c; setup-plt" cycle.
