[Dovecot] Dovecot 2.0.beta3: mdbox mailbox crashes upon login

[Thomas Leuxner]

Hi,

converted my personal mailbox from 'maildir' to 'mdbox' for testing today:

# dsync convert -u user at domain mdbox:~/mdbox

Set mail location to mdbox in 'mail.conf' and restarted server:

mail_location = mdbox:~/mdbox

Dovecot panicked instantly upon login with different clients. Tried to disable several plugins to no avail:
