No, the above is a bug fix that did not make it into rc1 but has now 
been committed.  It arose because the interface of a class in one of the 
modules was changed from .set_var(val) to .var = val and the need to 
change IDLE was not caught.  I imagine that checking that IDLE runs in 
not in the test suite.
