Bug#998718: Brasero fails (on Testing) burning an ISO image on a CD-RW

Wed Nov 10 20:12:22 GMT 2021

I again carried out a small experiment (as a simple user as I am) and 
precise,
or rather I correct, what was stated in a previous email.
Burning an ISO to a blank CD-RW (after: wodim dev=/dev/sr0 -v 
blank=fast) won't work either:
This is brasero-session.log:
