Yup -- that makes it tough to figure out with that bt, since the
problem doesn't appear to be in your code.
Can you post your objectValueXXX method implementation?
Can you also show the string in your array that you are setting as the
object value? (ie: print it in the debugger or NSLog(@"%@") on it.)

Hi Corbin,
Many thinks for the debug tip - it works a treat !
I'll just leave it there for the future.
Here is the stack trace when the exception is thrown.
I can't see where the problem is as the underlying code has clearly
used the attributed strings to draw the contents in the first place.
Is the mechanism of rendering different when I try to select a row ?

Break on objc_exception_throw and look at the bt; that should help
you find the source of the exception being raised.
