[Dovecot] Corrupted Index Cache

[Jeff Grossman]

I am starting to use Squirrelmail a little bit more to read my mail during
the day and I seem to be getting this error more frequently while using
Squirrelmail.  Just a coincidence or do you think using Squirrelmail might
have something to do with it?

Corrupted index cache file /home/vmail/jeff/dovecot.index.cache: record
points outside file

I am using Squirrelmail, IMAPProxy, and Dovecot 1.2RC3.  Here is a copy of
my dovecot -n.
