[Dovecot] doveadm quota get -u segmentation fault

Fri Dec 24 13:16:31 EET 2010

Hello!

I'm trying move to dovecot2 (centos 5.5, dovecot 2.0.8, dovecot
compiled/packaged via edited dovecot2.spec from fedora git).
Almost all fine, I can login via imap/pop3 and work with mail.

I get segfault error with "doveadm quota get -u user"

Here backtrace and other info:
