[Samba] Samba 4.0.5 git. Printer sharing broken?

[steve]

Version 4.0.5-GIT-50c476e
openSUSE 12.3 with CUPS driver on the DC which is printing OK from Linux 
clients joined to the domain.

Hi everyone

I have set up printing according to:
http://wiki.samba.org/index.php/Samba4/HOWTO#Step_13:_Setup_a_Printer_share

My smb.conf looks like this:
[printers]
     comment = All Printers
     path = /usr/local/samba/var/spool
     browseable = Yes
     read only = No
     printable = Yes

[print$]
     comment = Point and Print Printer Drivers
     path = /usr/local/samba/var/print
     read only = No

But testparm tells me otherwise (notice the browseable = No):
[printers]
         comment = All Printers
         path = /usr/local/samba/var/spool
         read only = No
         printable = Yes
         print ok = Yes
         browseable = No

[print$]
         comment = Point and Print Printer Drivers
         path = /usr/local/samba/var/print
         read only = No

Although I can't see the 'Printers and Faxes' share in W7 explorer, I 
see an empty screen at \\server\printers and when I right click I can 
choose 'server properties' and proceed to select the correct driver. The 
driver installs fine from a W7 client and the files appear at:
/usr/local/samba/var/print/W32X86/3

However, I cannot print anything from Windows. The printer does not 
appear and cannot therefore be selected even though the driver seems to 
be correctly installed.

This same config was working fine with 4.0.0. Any ideas what to do to be 
able to share the printer using the test branch?

Cheers,
Steve
