[Pkg-xfce-devel] Bug#770283: xfburn crashes when adding Data Composition files

as one can see, there is not much xfburn code active when the
SIGSEGV happens. I guess it is thread 1 which suffers it.
Now while there is still the possibility that xfburn started
the problem by subtle corruption of memory management, it
is strange that this does not happen on arch "amd64".
xfburn source code itself makes no differences between processor
In may 2014 i had a semi-private (german) conversation with an
Ubuntu "i386" user who experienced SIGSEGV in the GTK libraries
when starting a burn run. We involved the memory checker program
valgrind and the developer of xfburn.
Regrettably the case could not be solved because valgrind did
not find any wrongdoing in xfburn code, and because the entrails
of GTK are too complicated for me, valgrind, and the developer
Valgrind detected the memory problems earlier than the SIGSEGV
happened, but it could not show us the initial trigger in GTK.
(I'm glad that my own sports only deals with burner drives and
ISO 9660 filesystem entrails. It's so relaxing if you depend
only on command line, core operating system, and own code.)
If you feel apt to do in a shell session (aka terminal window):
sudo apt-get install valgrind
valgrind $(which xfburn) 2>&1 | tee -i /tmp/valgrind_messages
and then replay the user input which leads to the crash,
then please post the resulting file /tmp/valgrind_messages.
Have a nice day :)
