In an attempt to create a Squeak image for the iPaq, my last step was to
try to:
 Smalltalk abandonSources; condenseChanges

This caused an error:
 Error: Improper store into indexable object

I'd try to debug this, but I never really understood how sources, changes,
and those wacky CompiledMethods worked. Sorry. :(
