[Dovecot] Corrupted index files

[Tomi Hakala]

Hi,

I'm playing with Dovecot in a lab environment and got it in state
where it crashes on every incoming connection.

I moved mail spool from ext2 file system to a ReiserFS on a another
disk, mount point changed from /var/vmail to /spool/vmail. After that
I managed to open mailbox and I moved about 2000 messages from INBOX
to a subfolder.

Then I tried to open mailbox with POP3 and it didn't succeed, from 
that point pop3d and imapd died every time I logged in until I removed
all index files by hand.

This is what I have in logs.
