I get an explicit Notification that ClassDescription shouldn't be 
redefined, with the ability to proceed. Which indicates to me that 
you should be able to trap the Warning.

-----
ClassDescription should not be redefined! 
Proceed to store over it.

Select Proceed to continue, or close this window to cancel the 
operation.
-------

Doesn't look to me like a bug, unless the warning is covering 
something up.

This comes from
ClassBuilder>>name: className inEnvironment: env subclassOf: newSuper 
type: type instanceVariableNames: instVarString classVariableNames: 
classVarString poolDictionaries: poolString category: category 
unsafe: unsafe
