OK, I have a "crashed pipeline" with gdb attached on it near to me.
I posted traces on the bugzilla :
https://bugzilla.gnome.org/show_bug.cgi?id=692953
Perhaps it is better to continue the discussion on the bugzilla to do
not split/duplicating information.
But the bugzilla is buggy (had truncated my traces)
If you want them :
This is the stdios (nothing since yesterday) :
