I've been trying various combinations of configuration, with no luck, is 
it possible to enable more debug logging than mail_debug?

As a last-ditch effort I also tried the symlinking suggedted in 
https://wiki.dovecot.org/SharedMailboxes/Symlinks but this does not work 
either, I get a SUBSCRIBE BUG when I try and subscribe to the folder 
(which is visible) from Roundcube. (I am symlinking directly to the 
maildir folder, and not a sub-box, as I need access to the regular 
inbox)

How do I report this as a bug?  I can't seem to find a Dovecot issue 
tracker anywhere.
