samba - Apr 2007 - smbd segfaults when trying to browse printers folder

Greetings,

I just set up another samba server just for serving print queues.

Setting everything worked fine, including point-n-print, until I shut down 
the machine and put it in the rack.

Now, if you browse to the box, the printers are listed, and you can 
connect to them, print to them, etc. no problem.

If you click on the printers folder in the browse list, however, to view 
more detailed information, smbd segfaults.

Specs:  Samba 3.0.24, on Fedora Core 6 x86_64 (compiled myself).

Here's my very simple smb.conf and the log entry that is left behind when 
this happens.

If you want to browse them, shouldn't this be yes?

That doesn't answer why it segfaults, though...

Have you initialized the printer?  We shouldn't segv none
the less I admit.  Would you mind opening a bug report and
including the full, zgipped level 10 debug log ?



Thanks.
