Hi,
dovecot crashes with the following trace when accessing some Maildirs:
dovecot: 2007-05-16 13:30:09 Error: IMAP(6126360): file
index-mail-headers.c:
line 260 (index_mail_parse_header): assertion failed: (part != NULL)

dovecot: 2007-05-16 13:30:09 Error: child 6845 (imap) killed with signal 6
The command leading to the crash is (line wrapped for readability):
UID FETCH 1:214748367 (UID ENVELOPE BODYSTRUCTURE INTERNALDATE
RFC822.SIZE FLAGS BODY.PEEK[HEADER.FIELDS (Importance X-Priority
Priority X-PIM-INFOS
Content-Type Date)])
When I connect to dovecot and simply fetch with the following
command:
UID FETCH 1:* (ENVELOPE)
dovecot seems to updates its dovecot.index.cache files and the crash
never appears again. I have a mailbox that can be used to reproduce
the error.
Best wishes,
Jörg
