Cannot Blank or burn to CDRW disk with SuperGrub2

[psl]

Ubuntu 11.04, i386
brasero 2.32.1-0ubuntu2

My CDRW device:
scsi 1:0:0:0: CD-ROM HL-DT-ST DVD-RAM GH22NS30 2.00 PQ: 0 ANSI: 5

I needed to fix my Linux box that cannot boot so I burned Supergrub2 to my pocket CDRW disk. No problem. I fixed my PC with Supergrub2 disk.

I wanted to burn PartedMagic 6.6 to my pocket CDRW disk. I did this many times before but it was not working this time, I received message that there is no usable disk in my CDRW burner. I expected message that Disk has to be blanked before it can be used. It looked like my system is broken and cannot burn CDRW anymore.

I blanked my CDRW disk with wodim and it fixed the problem:
# wodim dev=/dev/scd0 blank=fast

Once the disk was blanked, it works as expected. I guess that SuperGrub2 disk triggers some bug in Brasero. All blank/burn was done on the same PC (Ubuntu 11.04) with the same disk and drive.

Steps to repeat the issue:
1) download and burn SuperGrub2 ISO disk to your CDRW disk.

2) try to burn (or blank) other ISO image to your CDRW disk with SuperGrub2 (use Braseiro or Gnome file manager)
