[Dovecot] doveadm quota get -u segmentation fault
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:

Better to use: WHERE mail='%n' and domain = '%d'> password_query = SELECT mail || '@' || domain as user, password as > password, '/mail/' || domain || '/' || mail || '/maildir' as userdb_home, > uid as userdb_uid, gid as userdb_gid, 'maildir:storage=' || (quota/1024) as > userdb_quota,Remove userdb_quota from here and add a userdb_quota_rule matching user_query's one. I'd also remove home/userdb_home from the above query and just use global settings, also not making home same as mail location (http://wiki2.dovecot.org/VirtualUsers/Home): mail_home = /mail/%d/%n mail_location = maildir:~/maildir:INDEX=~/indexes -------------- next part -------------- A non-text attachment was scrubbed...
