[syslog-ng] stupid question: syslogging plaintext non-syslog-format messages unchanged (netconsole)

[Nix]

So I'm trying to get the Linux kernel netconsole working, to diagnose
some nasty persistent panics... and after some struggle I've got most of
it working, but I can't make syslog-ng (3.0 from git as of tonight)
cooperate. The problem seems to be that netconsole is handing syslog-ng
completely bare text lines over UDP, and syslog-ng is persistently
trying to linebreak them at apparently random space characters, even
with the no-parse flag turned on.

Some specifics.

I'm receiving the netconsole messages with the following (trimmed down
from the real 500-line-long config, all global options preserved in this
trim, I'm pretty sure this is everything relevant but I haven't tested
this on its own yet 'cos it would break syslogging for a fairly large
network to actually replace the syslog-ng config with this):

,----
| options
|  {
|   keep_hostname(no);
|   create_dirs(1);
|   perm(0644);
|   dir_perm(0755);
|   log_fifo_size(1000);
|   use_dns(yes);
|   dns_cache(yes);
|   use_fqdn(no);
|   log_iw_size(5192);
|   flush_lines(100);
|   flush_timeout(1000);
|   stats_freq(3600);
|   chain_hostnames(yes);
|  };
| 
| source netconsole
|  {
|   udp(ip(0.0.0.0) port(24183) log_fetch_limit(100) flags(no-parse no-multi-line));
|  };
| 
| # A bare template, for netconsole messages.
| template bare
|  {
|   template("$MSG\n");
|   template_escape(no);
|  };
| 
| destination netconsole
|  {
|   file("/var/log/$HOST-netconsole.log"
|        template(bare));
|  };
| 
| log
|  {
|   source(netconsole);
|   destination(netconsole);
|  };
`----

but this is not enough. Most of the time the same message is received
over an ordinary syslog source, too, so I can compare the two. If the
syslogged message reads:

,----
| Oct 20 21:17:53 mutilate warning: : [ 6783.237435] pktcdvd: Fixed packets, 32 blocks, Mode-2 disc
| Oct 20 21:17:53 mutilate warning: : [ 6783.238541] pktcdvd: write caching control failed
| Oct 20 21:17:53 mutilate warning: : [ 6783.238547] pktcdvd: 55 10 00 00 00 00 00 00 14 00 00 00 - sense 05.00.00 (Illegal request)
`----

the netconsole message that's logged using the configuration above reads

,----
| [ 6783.237435] pktcdvd: Fixed packets,
| 32 blocks,
| Mode-2 disc
| [ 6783.238541] pktcdvd: write caching control failed
| [ 6783.238547] pktcdvd:
|  55
|  10
|  00
|  00

|  00
|  14
|  00
|  00
|  00
|  -
| sense 05.00.00
|  (Illegal request)
`----

This is obviously not sane. Removing the no-multi-line flag doesn't
change anything at all (I only added it in desperation, because I *want*
linebreaks in the original message to be reproduced in the output: I
just don't want *more* linebreaks than are present in the original
output), so that's not it either. I'm logging kernel messages using

,----
| source local
|  {
|   unix-stream("/dev/log" flags(no-multi-line));
|   internal();
|   file("/proc/kmsg" program_override("kernel: ") flags(kernel no-multi-line));
|  };
`----

and things hanging off that, without incident: no random linebreaks or
anything.

So, what am I missing? It's probably incredibly obvious, but I've blown
several hours hacking at configs and digging through the syslog-ng
source and have seen nothing to indicate what's going on...
