Comment(by ehuelsmann):

The source of this behaviour is the fact that in some cases the 'format- control slot in the built-in condition doesn't get set.

When that happens, the print-object code in print-object.lisp doesn't get triggered to print the nice message, but rather passes control to the standard object printing routine (which prints the ugly output above).
