Hi,

this bug is also discussed at the german Ubuntu forum
and brought to the attention of the upstream programmer
of xfburn. It appears as if it was depending on particular
installation environment.
  
We can believe that the author tested this use case before 
release. I myself worked with it on non-standard xfce equipment
on Debian 6.  
The german bug is with Lubuntu 14.04.
  http://forum.ubuntuusers.de/topic/brasero-3-10-0-schliesst-cd-dvd-nicht-ab/2/
(The thread began about Brasero. But since i do not know
 how to get the attention of Brasero maintainers, i
 proposed to hunt down the mentioned bug in xfburn.)

There is some problem indicated by valgrind on the machine
of the german user: 
  ==3172== Invalid read of size 4 
  ==3172==    at 0x5217370: ??? (in 
/usr/lib/i386-linux-gnu/libgobject-2.0.so.0.4000.0)
  ...
  ==3172==    by 0x4B8A7DD: gtk_object_destroy (in 
/usr/lib/i386-linux-gnu/libgtk-x11-2.0.so.0.2400.23)
  ==3172==    by 0x12BC9B: ??? (in /usr/bin/xfburn)
  ==3172==    by 0x521E728: g_cclosure_marshal_VOID__VOIDv (in 
/usr/lib/i386-linux-gnu/libgobject-2.0.so.0.4000.0)
  ==3172==    by 0x521CCCD: ??? (in 
/usr/lib/i386-linux-gnu/libgobject-2.0.so.0.40
  ==3172==  Address 0x150 is not stack'd, malloc'd or (recently) free'd

If Ubuntu could provide an xfburn package with debugging
information, then valgrind could probably tell more.

An apport crash file of a different run indicates a stack
trace without any xfburn function call in it.
So i (as bystanding libburn programmer) suspect that the
memory management gets damaged by the valgrind catch, and
that it stumbles ahead until it finally crashes.

It might still be some way to go after we learn about the
xfburn parameters in the valgrind report.
It is unclear whether xfburn or the desktop libraries are
to blame.

Very helpful would be a valgrind run of xfburn on some other
Ubuntu desktop, in order to see whether similar memory access
errors are detected. (Would help even without debugging-ready
xfburn.)

Have a nice day :)
