Subject: SIGSEGV in Brasero

Hello, I'm am also getting a segfault.

To reproduce: It happens when I attempt to burn an ISO file to a CD-RW. It happens the moment I click the "Burn" on the Image Burning Setup dialog window.

My system:

```
christopher@theoden ~$ neofetch --stdout

```

I rebuilt Brasero with the following command, with the aim to get debug symbols, though I don't seem to be getting them...

```
guix build brasero --with-debug-info=brasero --with-debug-info=glib
```

Then here is the backtrace I got. My gdb skills are a bit rusty... if somebody can suggest better commands I can provide additional output.

```
