I've never used the command-line tools before, and I can't say I'm very
well-versed in them.  I ran a few that looked like obvious candidates;
their output is below.  While I did get output similar to what Nautilus is
reporting, I couldn't get an exact match, and none of these commands caused
the dmesg error to show up again.  Here's what I tried:

Of course, even though I couldn't reproduce the kernel message, the fact
that none of these succeeded does suggest, at least, that the problem isn't
just with Nautilus.  The last is what I thought Nautilus was running, given
what's in nautilus_burn_recorder_write_growisofs, but it doesn't look like
it.  If you can suggest other commands to try, especially if you know what
Nautilus might be running or how I might get some more detailed
diagnostics, I'd be happy to try them out and pass them along.

Thanks.
