www.mediaciety.de info@mediaciety.de This is scenario that cause segmentation fault in my Dovecot. Maybe I do something wrong, but I don't know what...

We run: mailbox_delete mailbox_delete do: mailbox_open(box) < 0 and after we have: box->v.delete(box) which run index_storage_mailbox_delete

index_storage_mailbox_delete do: mailbox_close(box); and now mailbox is closed (this close box->view and mailbox open)

Try to delete folder, but can't do this... example becaus it is system folder, or NFS failure... set error message and return -1.

Now we are returning to mailbox_delete.

And we have: if (ret < 0 && box->marked_deleted) and this is true mailbox_mark_index_deleted(box, FALSE) if (box->marked_deleted && del) this is false mail_index_transaction_begin(box->view, trans_flags); mail_index_view_ref(view) and segmentation fault, because view is 0x0
