i saw two crashes in my syslog with dovecot, and google did not report any known problems. i have no problems using dovecot, thus bugreport is just for information.

following information: ubuntu gutsy gibbon server amd64 ext3

outlook 2003 & 2007, just retrieving mails. mails have been migrated via imapsync 2 days before to this server. dovecot is imap-server and LDA.

has been seen with two different users, following syslog entries:
