brasero crashed with SIGSEGV in g_closure_invoke()

[Gionn]

Reproducibile with: burn an ISO, enable simulation, wait simulation complete and ask dialog appear to proceed to burning, click burn, brasero try to eject/inject tray (but this is a laptop), return an error. When I retry to burn (but without simulation) the same iso etc, when I press on burn it crash.
