When imap_done() got called before a connection is setup, it would try to "finish up" and dereffed a NULL pointer. Test case 1553 managed to reproduce. I had to actually use a host name to try to resolve to slow it down, as using the normal local server IP will make libcurl get a connection in the first curl_multi_perform() loop and then the bug doesn't trigger.
