OK, definitely looks like that IMAP server is broken.  Using the test
account, a list of all folders gives this:

a002 list "" *
* LIST (\NoInferiors \UnMarked) "/" junk-mail
* LIST () "/" sent
* LIST () "/" a
* LIST () "/" a/b
* LIST () "/" INBOX

A list of the 'a' folder gives the following:

a003 list "" a/%
* LIST () "/" a/
* LIST () "/" a/b

That 'a/' entry should not be there.  It is not a valid folder.  At the
very least it should have a '\Noselect' flag.  But the IMAP server is
telling us it is a valid folder, so that's what we have to assume.  We have
no way of knowing before we perform an operation on it whether that
operation will be successful or not.
