I have some archived mails in compressed (by bzip2) mboxes and I would like to read them via imap Unfortunately it looks like dovecot crashes when tries to read them :(

#v+ kjonca@alfa:~/Mail/Old/Junk%sudo /usr/sbin/dovecot -n
[sudo] password for kjonca:

Then I try to read mailbox:

#v+ kjonca@alfa:~/Mail/Old/Junk%mutt -f \=\#Old/Junk/2008.bz2 #v-

In logs is: #v+ 2010-03-22 17:03:05 imap-login: Info: Login: user=<kjonca>, method=DIGEST-MD5, rip=127.0.0.1, lip=127.0.0.1, secured 2010-03-22 17:03:05 IMAP(kjonca): Info: Loading modules from directory: /usr/lib/dovecot/modules/imap 2010-03-22 17:03:06 IMAP(kjonca): Info: Module loaded: /usr/lib/dovecot/modules/imap/lib20_mail_log_plugin.so 2010-03-22 17:03:06 IMAP(kjonca): Info: Module loaded: /usr/lib/dovecot/modules/imap/lib20_zlib_plugin.so 2010-03-22 17:03:06 IMAP(kjonca): Info: Effective uid=1000, gid=1000, home=/home/kjonca 2010-03-22 17:03:06 IMAP(kjonca): Info: Namespace: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes 2010-03-22 17:03:06 IMAP(kjonca): Info: maildir: data=~/Mail/def:LAYOUT=fs:INBOX=~/Mail/def 2010-03-22 17:03:06 IMAP(kjonca): Info: fs: root=/home/kjonca/Mail/def, index=, control=, inbox=/home/kjonca/Mail/def 2010-03-22 17:03:06 IMAP(kjonca): Info: Namespace: type=private, prefix=#Old/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes 2010-03-22 17:03:06 IMAP(kjonca): Info: mbox: data=~/Mail/Old 2010-03-22 17:03:06 IMAP(kjonca): Info: mbox: INBOX defaulted to /home/kjonca/Mail/Old/inbox 2010-03-22 17:03:06 IMAP(kjonca): Info: fs: root=/home/kjonca/Mail/Old, index=, control=, inbox=/home/kjonca/Mail/Old/inbox 2010-03-22 17:03:06 IMAP(kjonca): Info: Namespace #Old/: Using permissions from /home/kjonca/Mail/Old: mode=0700 gid=-1 2010-03-22 17:03:50 dovecot: Error: child 27392 (imap) killed with signal 11 (core dumped) #v-

#v- I tried to recompress these mboxes with gzip and dovecot perfectly works with them.
