After a recent update of dovecot to 2.2.devel (d81a83b) I started to get
errors like that:

Any possibility you could provide us with stack trace using gdb? If possible, install debuginfo packages, and run gdb /path/to/pop3 /path/to/core bt full and send it to list, please! This would make it a lot easier to debug your issue. Thank you! Aki Tuomi Dovecot Oy
