migration from cyrus; seg fault at mail_namespaces_get_root_sep
Hi all,
I am currently trying to migrate from cyrus to dovecot on a new system.
Though only few accounts, I decided to use the mdbox format.
To convert I use cyrus2dovecot first, then I use dsync to import the
mailboxes.
For compatibility I set the namespace of inbox to prefix = INBOX. and
separator = . (as described here:
http://wiki2.dovecot.org/Migration/Cyrus
http://wiki.dovecot.org/Namespaces).
This works except that the clients (mutt and Thunderbird) show an
additional folder/mailbox "INBOX" below the inbox. How can I fix that?
Should I add a prefix during conversion and not change the namespace
config? On disk, the subfolders are next to INBOX.
Well, I then tried to set list = children instead of "yes" for
namespace
inbox. On login a segfault occurs with this setting. See the information
and backtrace below.
Regards,
Vincent
