Title:
  direct burning of data-cd results in unreadable disk

Status in “brasero” package in Ubuntu:
  Confirmed

Bug description:
  If you burn a data-cd and choose the first option, "burn directly, do
  not save on hard disk", (I don't know how it is labeled in English, my
  GUI is German) brasero will burn and tell that it did successfully,
  but the disk is unreadable.

  If you disable and burn with first creating an image, the disk is
  okay.

  I tried it with audio-cd, it is not affected.

  Appeared on two laptops, mine being a Toshiba C650D and my
  girlfriend's being a Packard Bell TK85. Workaround worked on both
  laptops.

  Please test on other systems to confirm!

  
  Trying to read disk:

  /var/log/syslog remains quiet if you wait for automount. Trying "mount
  -t iso9660 /dev/dvd /media/test" results in error-message: ISOFS:
  Unable to identify CD-ROM format.

  Trying "mount -t iso9660 -o loop /dev/dvd /media/test" results in
  longer message:
