debian/patches is in the unpacked source as brought to you by 'apt-get source 
brasero'

apt-get source brasero

(this is from my fully updated sid box as of today, your 'stable???' will 
differ)

Fetched 3,254 kB in 6s (515 kB/s)                                                                                    
dpkg-source: info: extracting brasero in brasero-3.4.1
dpkg-source: info: unpacking brasero_3.4.1.orig.tar.xz
dpkg-source: info: unpacking brasero_3.4.1-2.debian.tar.gz
dpkg-source: info: applying 03_cue-invalid-frame-75.patch

$ cd brasero-3.4.1/

$ cp /tmp/check-child-status debian/patches/

$ echo check-child-status >> debian/patches/series 

$ cat debian/patches/series 
03_cue-invalid-frame-75.patch
check-child-status

$ dpkg-checkbuilddeps  # to check you have all build-dependencies installed

$ dpkg-buildpackage

and after that you will shortly see:
dpkg-source: info: applying check-child-status

other patches are applied on unpack/extracting stage by dpkg-source, when you 
ask apt-get source to fetch the source for you.

When finished, see the brasero*.deb in the upper directory (your patched 
package). Remove any previous brasero package you might have:

apt-get --purge remove brasero

install yours:

dpkg -i your_new_brasero*.deb


Use 'gconf-editor' to find brasero plugin configuration, and adjust prioroties. 
Also with a started brasero instance, check Edit | Plugins to see what is in 
use. Finally the log should tell you, since plugins yell some debugging 
messages.

Also, reporters claim that just burning ISO image works.
What does not work is "to burn a Data Project directly from disk".

See what you have installed (^ii means installed)

dpkg -l | awk '$1~/^ii/ && $2~/^brasero/ {print $1 " " $2 " " $3}'

or:

apt-cache policy brasero

(apt-get install brasero - to install from sources configured in sources.list, 
i.e. Debian archive, and: dpkg -i *.deb to install a local deb)

On "Burn" you should be able to select one?

Hm, you created an ISO and burnt that? I guess we need a "Data Project" as 
reporters claim to be problematic...

Ahem.

Hm, it spits messages on its stdout and stderr, doesn't it?

Okay, thanks for the try.

The initial bug report claims 2.30.3-2 to be buggy, further reports claim this 
bug manifests with newer versions too, up to 3.4.1-2.

Get one from Debian stable?

apt-get install brasero

(apt-get install brasero=version also works)

'apt-cache policy brasero' to see your options, depending on your sources.list 
entries. But if you run stable, stay on it for a while :)
