Couple of problems afaict:

1 We are not using Fallback on qemu, because "import glive" will
succeed. Maybe there is a way to detect if the hardware actually have a
cam that glive can use.
2 There are no pictures on the drive... Sort of funny but... it's
probably a real problem for the qemu testing (we don't want people to
have to add pictures to their images to have the thing starting up...)

Can you remember me the exact reason why having a picture is mandatory?
