Hello,
we are using dovecot v1.2.10 on debian stable (lenny) systems with 
mailboxes on NFS, and we are facing this quite ugly crash:

2010-04-27 10:59:06 IMAP(<mailbox>): Panic: file mail-index-sync-ext.c:

the only solution we have found is to delete the dovecot.index* files, 
and let dovecot regenerate them at the next access.

could you please give it a look?

Thanks in advance,
Sandro
