OK, here's the problem:

  1217      } else if ((p = mboxname_isusermailbox(oldname, 1))) {
  1218          if (!strncmp(p, userid, config_virtdomains ? strcspn(userid, 
"@") :
  1219                       strlen(userid))) {
  1220              /* Special case of renaming inbox */
  1221              access = cyrus_acl_myrights(auth_state, oldacl);
  1222              if (!(access & ACL_DELETEMBOX)) {
  1223                r = IMAP_PERMISSION_DENIED;
  1224                goto done;
  1225              }
  1226              isusermbox = 1;
  1227          } else if (config_getswitch(IMAPOPT_ALLOWUSERMOVES) &&
  1228                     mboxname_isusermailbox(newname, 1)) {
  1229              /* Special case of renaming a user */
  1230              access = cyrus_acl_myrights(auth_state, oldacl);
  1231              if (!(access & ACL_DELETEMBOX) && !isadmin) {
  1232                  r = (isadmin || (access & ACL_LOOKUP)) ?
  1233                      IMAP_PERMISSION_DENIED : IMAP_MAILBOX_NONEXISTENT;
  1234                  goto done;
  1235              }
  1236          } else {
  1237              /* Only admins can rename users (INBOX to INBOX) */
  1238              r = IMAP_MAILBOX_NOTSUPPORTED;
  1239              goto done;
  1240          }

Line 1238 in particular (of mboxlist.c).  This might not match up exactly
for you because you don't run all the same patches, but the concept is there.
If you're renaming from a user mailbox to not a user mailbox, it fails during
the rename part.

This probably works for you because you're using an alternative hierarchy
separator and mboxname_isusermailbox is probably bogus/broken in that case.
Man I hate Cyrus's multiple namespace methods and lack of clarity in name
conversion sometimes.  If it was a web app it would have XSS bugs.


So yeah, you don't get this behaviour because it's masked by a different bug.
*sigh*.  I'll come back and patch this when I get back from the gym.
