[Samba] smb panic when adding printer with apw

[Thorsten Leiser]

Hi,

I'm using samba 3.3.15 as domain member in an w2k8 ad. We're using the 
w2k3/xp add printer wizard to add a printer to the server. Since the 
update from 3.2.15 to 3.3.15 the apw fails when clicking on the "finish" 
button. At the same time a smb panic occurs and fills the smbd log with 
the lines below.

Does anybody know what's wrong?
Thanks for your assistance.
