Do you have ZEO set to use a persistent cache? If so, remove it and  
try again.
If not:

It looks like your database is corrupted.  Have you tried using  
the .old file
left by the pack?  If that doesn't work, you'll probably need to use  
a backup.

Otherwise, it might be possible to replace this object.  I don't  
think ApplicationManagers have any precious state.  They really  
shouldn't be persistent at all IMO.  You might be able to use zopectl  
debug to replace this object with a new instance.
