class list improperly terminated

[F. Heitkamp]

No matter what I can't seem to get rid of this error.  I've tried 
uninstalling, reinstalling, different compilers etc.  Nothing has
worked.

/usr/GNUstep/Local/Applications/GNUMail.app/ix86/linux-gnu/gnu-gnu-gnu/GNUMail: 
Uncaught exception NSInternalInconsistencyException, reason: class list 
improperly terminated

This error comes from the file NSUnarchiver.m at
    692       if (info != _GSC_NONE)
    693         {
    694           [NSException raise: NSInternalInconsistencyException
    695               format: @"class list improperly terminated"];
    696         }
    697       return;
    698     }

Can anyone explain or point me to a explaination of what could be going
wrong?  What is being unarchived?  Is this function ultimately depending
on some external library?

This is what I used to compile GNUStep:

GNU assembler 2.12.90 20020501
gcc (GCC) 3.2
