You don't need to remove that from this Array... there is, after all,  
a reason
for that pointer to the obsolete class. So, there used to be a class  
PackageList,
which turned out to be not too usefull. So it was removed, but the  
entry in
the World Menu was not deleted. Thus a pointer to the deleted class  
remained.

You can just evaluate

TheWorldMenu removeObsolete

and after that,

SmalltalkImage current fixObsoleteReferences.

should not get you any complaints anymore.

There are a number of these things to be done for the 3.9a image...
that's why it's alpha, after all. And in a perfect world, we would have
an automatic build process that would catch and force us to fix
those early on...
