gnome-disks --restore-disk-image foo.iso no longer opens the disk image restoration dialog, it just opens the gnome-disks UI, and consequently the open with Disk Image Writer option in Nautilus doesn't work as it should. Looking at the code, it looks like it should also be checking that the file given as argument should be a regular file, but that doesn't happen either; if I pass let's say --restore-disk-image /tmp there are no complaints anywhere and the main UI just opens. This used to work in F-22. $ rpm -q gnome-disk-utility gnome-disk-utility-3.18.2-1.fc23.x86_64
Checking some earlier builds, this broke somewhere between 3.16.2 and 3.17.2. Looks like the combination of G_OPTION_ARG_FILENAME and the corresponding g_variant_dict_lookup call for restore-disk-image doesn't work. If I change restore-disk-image to G_OPTION_ARG_STRING instead, things work again. So this commit by Matthias is probably the culprit: https://git.gnome.org/browse/gnome-disk-utility/commit/?id=7c36385393d3f2a8b7e9837519a50cb97514860a
Fixed in https://git.gnome.org/browse/gnome-disk-utility/commit/?id=5d959dc1c877bac67ebaa5d3957233fb1191dfcd
