Comment 10 for bug 397980

Same thing happened to me, but all the mail is still in the file in my
 case ... it's just no longer *listed* by evolution.

Type
grep "^Date" .evolution/mail/local/<thenameoftherenamedfolder>
Date: Wed, 10 Mar 2010 17:01:10 -0800
...
Date: Fri, 18 Jun 2010 12:49:11 -0400

and/or

grep "^Date" .evolution/mail/local/<thenameoftherenamedfolder> | wc -l
159

My <thenameoftherenamedfolder> has a first date of
Date: Wed, 10 Mar 2010 17:01:10 -0800,
which is correct and I can see all the 159 emails if I look at the
actual file, even though evolution is only telling me that there are
only 14, going back 3 days.

Until I figure out the indexing problem, I did this:
dan@descartes:~$ mkdir .evolution.backup
dan@descartes:~$ cp -rf .evolution/ .evolution.backup/

Hope you recover everything.
