Title:
  Brasero calculates wrong checksum after burn ISO to CD

Status in “brasero” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: brasero

  After burning a CD from an ISO file, Brasero reports an error saying
  checksum from ISO file and burned CD do not match. ("Some files may be
  corrupted on the disc").

  However, CD is fine and all files were burned correctly. I did a
  manual verification using md5sum on both the ISO and on the burned CD,
  and they DO match.

  Steps to reproduce:
  - In Nautilus, right-click an .ISO file (i used ubuntu-9.04-desktop-i386.iso) and select "Write to Disc". 
  - Click "Burn"

  After recording, it says "Some files may be corrupted on the disc".

  Opening up the logfile, near the end theres the line that triggered
  the error:

  BraseroChecksumImage Setting new checksum (type = 2)
  2602036235674bdd37d297dadd7547dd (66fa77789c7b8ff63130e5d5a272d67b
  before)

  Steps to Verify:
  - Check the ISO hash: md5sum ubuntu-9.04-desktop-i386.iso
  ( it says 66fa77789c7b8ff63130e5d5a272d67b, same checksum as in Ubuntu documentation https://help.ubuntu.com/community/UbuntuHashes )
  - Check the CD hash: md5sum /media/cdrom (again, 66fa77789c7b8ff63130e5d5a272d67b)
  - Create ISO from CD using Brasero, and then check md5sum: 66fa77789c7b8ff63130e5d5a272d67b

  So Brasero, for some reason, is not calculating the burned CD checksum
  correctly.

  I tried with the same ISO twice, and then with another ISO (the one i
  am attaching). The 3 discs were OK but in all Brasero reported this
  error.

  PS: This is my 1st bug report, im new to Ubuntu, so I apologize theres
  anything incorrect in the report format.
