[Dovecot] namespace list not working in dovecot 1.2 revision 9027:421393827a81

In my config that has worked for some time I have:

namespace private { separator = / prefix = ~/ hidden = yes list = no # for v1.1+ }

1 list "~/" * 1 OK List completed. 2 list "~/" % 2 OK List completed.

I _think_ that the last time I tested this was 2 weeks ago but it
might have been 1 week ago.

Thanks, Jonathan
