I just want to report that testing this patch worked fine in my case.
And I leave the surprising – actually not anymore after your analysis –
to my answer to the other report.

First, here is how I built the package libburn4.

        $ debcheckout -p libburn4
        $ git svn clone svn://svn.debian.org/svn/pkg-libburnia/trunk/libburn/ libburn-debian
        $ git svn clone http://svn.libburnia-project.org/libburn/trunk
        $ cd libburn
        $ ln -s ../libburn-debian/debian debian

Search for the latest 1.2.2 commit with `git log`.

        commit 0a14ff40d0f62264ed42412e11f7d7dc40ed9792
        Author: scdbackup <scdbackup at fff8544e-141b-0410-a922-c1ea1f00b384>
        Date:   Mon Apr 2 17:30:19 2012 +0000
        
            Updated change log
            
            git-svn-id: http://svn.libburnia-project.org/libburn/trunk@4693 fff8544e-141b-0410-a922-c1ea1f00b384

Get that into an own branch.

        $ git checkout -b 1.2.2 0a14ff

Search for the fix I want to test with `git log` and the sting 4762.

        commit c74e6964a3be6b5b6365e3509792043aff55f26a
        Author: scdbackup <scdbackup at fff8544e-141b-0410-a922-c1ea1f00b384>
        Date:   Sun Jun 17 17:33:26 2012 +0000

Cherry pick that.

        $ git cherry-pick c74e6964a3be6b5b6365e3509792043aff55f26a
        error: could not apply c74e696... Improved reported number of missing bytes in case of track source shortage
        hint: after resolving the conflicts, mark the corrected paths
        hint: with 'git add <paths>' or 'git rm <paths>'
        hint: and commit the result with 'git commit'
        $ git diff
        $ vim cdrskin/cdrskin_timestamp.h
        $ git add cdrskin/cdrskin_timestamp.h
        $ git commit
        [1.2.2 1c15d96] Improved reported number of missing bytes in case of track source shortage

        $ dch

Since this is from Git/SVN do not forget to create the needed files.

        $ ./bootstrap
        $ debuild -b -us -uc
        $ sudo dpkg -i ../*_1.2.2-2.1*deb

It works as expected.

        BraseroBurn: (at burn-libburn-common.c:218) BraseroLibburn Premature end of input encountered. Missing: 48709632 bytes
        BraseroBurn: (at burn-job.c:1787) BraseroLibburn called brasero_job_get_session_output_size

        BraseroBurn: (at burn-job.c:1140) BraseroLibburn finished with an error
        BraseroBurn: (at burn-job.c:1174) BraseroLibburn asked to stop because of an error
        	error		= 15
        	message	= "Ein Fehler trat beim Beschreiben der CD/DVD auf"


Thanks,

Paul
