[Dovecot] file mail-transaction-log-view.c: assertion failed (v1.0.12)

[Uldis Pakuls]

Hi all.

Looking at previous weeks logs I discovered strange errors: "file mail-transaction-log-view.c: assertion failed" 

dovecot v 1.0.12

Server is hosting  more than 500 virtual users. It is compleate dovecot error log; only my own mailbox is affected ...and imap folder affected is "dovecots mailing list" :)
While "Corrupted transaction log file" as far as I know is not error to care about much, "assertion failed" is something new. 

maibox are accessed only by dovecet and dovecot's LDA.
