Thanks for all the suggestions. In the end, I took a scratch server, installed Cyrus on it and was able to import the mailbox dump file without any problem. On the server I was having the problems with, I reinstalled Linux and Cyrus, and imported the mailboxes just fine. I've no idea what was going wrong before(!).
