This causes a 'could not write' error in nautilus-cd-burner.

With --force cdrdao works fine.

> Thanks for your bug. What version of Ubuntu do you use? What error do you have
with nautilus-cd-burner and what are you trying to do? It doesn't use cdrdao to
write CDs but cdrecord
...
I'm using dapper (but I haven't checked if cdrdao still has the problem). The
error n-c-b gives is really generic and I don't want to waste a disc to see it
again. It happened when I was trying to copy an audio cd by right-clicking on
the cd icon on the desktop and clicking "Copy Disc...".

n-c-b does use cdrdao for CUE and TOC files, but not for ISO. The code in
nautilus-burn-recorder.c is:
        if (track->type ==  NAUTILUS_BURN_RECORDER_TRACK_TYPE_CUE) {
                argv = g_ptr_array_new ();
                g_ptr_array_add (argv, "cdrdao");
[...]
        } else {
                argv = g_ptr_array_new ();
                g_ptr_array_add (argv, "cdrecord");"
