samba - Jan 2012 - printing issue after update to 3.6.1

Hello,

we've updated to 3.6.1 yesterday, and since encounter
problems with printing for some users. There's a
descriptive error in the log.smbd, but I can't see
what to do about it really (the rest of the,
admittedly fairly ancient system, is the same base
system as the previous 3.5.5 - only a couple of security
updates were patched in during downtime).

The message in log.smbd is:

  adminpc-rmarx (158.64.1.188) connect to service SuperJam PCL6 initially as
user Administrator (uid=1003, gid=100) (pid 15885)

And indeed, looking into the spool directory, the file
names which used to encode the jobid now don't any more.
For illustration, a few old spooled jobs in the right
format as well:

So, for some reasons, jobid gets lost. Strangely enough, the file size is also
zero.

I'm sort of lost what would cause this. The thing I could
imagine is our fairly ancient cups on the system (1.2.7)
and that maybe 3.6.1 doesn't support some legacy CUPS API stuff that
3.5.5 still did. That's the only straw I'm holding onto.

Can anyone help out here?

Greetings,

Stefan Winter

The spoolss print job file open code-path has changed recently, looking
at print_spool_open() it looks like the job file is created without
taking the print jobid into account.

Please raise a bug with your logs attached.
