dovecot - Oct 2010 - Panic: file index-search-result.c .. assertion failed: (next_uid == mail->uid)

Hello,

with 2.0.5-0~auto+9 (6ea01abfaea9), haven't seen it earlier (but
of course index files have changed):

Oct  7 09:40:09 host dovecot: imap(user): Panic: file index-search-result.c:
line 87 (search_result_update_search): assertion failed: (next_uid ==
mail->uid)

when SELECTing virtual folder "sent" (.sent/dovecot-virtual is
INBOX
  header return-path lutz at pressler.de 
), IMAP session is terminated.

After moving .sent/dovecot.index[.log], everything works fine again.
I can send you the broken(?) index files, if appropriate.
