Unexpected data in output section

[Andreas Moroder]

Hello,

I found this strange error in the samba logs so I thought that I can 
post to the internals mailing list to get help.

I try to print via samba to a printer defined as


[rechnungen]
path = /var/spool/smb
create mask = 0700
printable = Yes
print command = /usr/local/smb2pdf/smb2pdf /var/spool/smb %s %u %U %J

and get this error message in my lsamba logs.

Error: Unexpected data in output section:
       2
Exiting.
Errors encountered.  No output created.
Done.  Input errors, so no output created.


Can anyone please tell me what's the source of this strange error that 
is so different from all log entries ?

Thanks
Andreas
