Bug#716702: brasero: Corrupt files in DVD-R burning

[rpnpif]

Package: brasero
Version: 2.30.3-2
Severity: important


Burning files on a DVD-R got corrupted files.
The files sizes are good but not their contents.

For this burning, the logical buffer was often empty, but burnfree was enabled.

K3B works fine in all case (growisofs) with the same difficulties of the logical buffer.
So, is Brasero manages fine the burnfree capacity ?
