Is it logging any other errors anymore? I can't really see how the code
is broken to cause this. Can you again reproduce it and send me that
mailbox's dovecot.index and dovecot.index.log files and the command that
crashed it?

Or getting a core dump and gdbing it and printing mail->uid and next_uid
values could also show something useful.

No need to delete anything.
