Thanks for all the suggestions.  I changed the function based on them, 
and now it dies the fifth or sixth time I access it, but on the third 
time I get a more friendly error message:

[NSCFString valueForProperty:]: unrecognized selector sent to instance 
0x1b90e0

So at least there's progress.  Thanks again!
