IMAP mailbox not selectable in browser

[Olaf Hering]

I have two mailboxes named "foo" and "foo.bar" on an IMAP server. If I
want to change into "foo", mutt only shows that entry as a directory. It
can only be selected if the name is specified manually. Both mailboxes
are apparently properly offered in claws. I wonder what makes mutt think
"foo" is a folder. Looking at the mutt -d 255 output:

$ grep -C1 foo .muttdebug0

Is there a chance I misconfigured mutt, or should it rather recognize
that "foo" itself is also a mailbox unconditionally?

To open a folder that also has children, use <space> instead of <enter>
in the browser.

$ grep -C1 foo .muttdebug0
[2018-10-28 09:41:36] 4< * LIST (\HasNoChildren) "." "unrelated"
[2018-10-28 09:41:36] 4< * LIST (\HasChildren) "." "foo"

In this line, the IMAP server is telling mutt that foo has children.
