[Dovecot] 2.0.2 : crashes with LDA

[Jakob Curdes]

Hello,
I just migrated to 2.0.2 and see some

<xx at localhost.redirectme.net>  (expanded from<xx at localhost>): Command died with
     signal 6: "/usr/local/libexec/dovecot/dovecot-lda  -c /etc/dovecot2.conf".
     Command output: doveconf: Panic: file settings-parser.c: line 1838
     (settings_copy_deflist_unique): assertion failed: (dest_count == ccount)
     doveconf: Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0

This does not happen always; most mails get delivered normally through the LDA.
A command line call of doveconf yields no problems.

Any hints?

Best regards,
