I thought I had, let's try again.

right-click on ISO image, select 'write to CD'.

I get a preperation dialog which is then followed by a dialog which says
"Error writing to disc\nThere was an error writing to the disc".

In the meantime I'm monitoring the processes list and see this:

eve:[~]% ps aux | grep burn
anand    17375  0.0  0.0   2348   592 ?        S    00:34   0:00 /usr/lib/nautilus-cd-burner/mapping-daemon
anand     7792  5.9  1.4  24348 15092 ?        S    23:49   0:00 /usr/bin/nautilus-cd-burner --source-iso=/home/anand/Desktop/data.iso
anand     7808  5.0  1.8  18448 18448 ?        DL   23:50   0:00 cdrecord mmap fs=16m dev=/dev/hdc -dao driveropts=burnfree -v -data -nopad /home/anand/Desktop/data.iso
anand     7812  0.0  0.0   3020   736 pts/14   D+   23:50   0:00 grep burn

So, somehow cdrecord is invoked incorrectly which causes things to fail.

I've done a full -ff -F and saved the resulting files, and in this trace
set I can see cdrecord outputing something and then exiting.  Shall I
send these out-of-band to you?
