Comment 2 for bug 514798

The merge proposal doesn't actually fix this bug as we can see that not adding '--iso' has no effect on the image used:

[ 9:31AM 11147 ] [ bdmurray@impulse:~/source-trees/usb-creator/main(b1a547a✗) ]
 $ usb-creator-gtk /misc/isos/ubuntu/lunar-desktop-legacy-amd64.iso
xorriso 1.5.4 : RockRidge filesystem manipulator, libburnia project.

xorriso : NOTE : Loading ISO image tree from LBA 0
xorriso : UPDATE : 774 nodes read in 1 seconds
libisofs: NOTE : Found hidden El-Torito image for EFI.
libisofs: NOTE : EFI image start and size: 1300333 * 2048 , 8496 * 512
xorriso : NOTE : Detected El-Torito boot information which currently is set to be discarded
Drive current: -dev '/home/bdmurray/Downloads/jammy-desktop-amd64.iso'

Additionally, the argument parsing routine of usb-creator-gtk has not changed.
