This one should be async as you are not going to be able to catch
errors otherwise.
ovirt_foreign_menu_set_current_iso_name(..)
and in the async callback which is called when it's done, you can revert
to the previous ISO name if there was an error.

Should be g_free I think?

Rather than relying on ovirt_foreign_menu_start() in
remote_viewer_iso_list_dialog_refresh_iso_list() eventually calling
'notify::files', I'd introduce a proper async API which would allow you
to cancel, catch errors, ...
ie:
ovirt_foreign_menu_get_files_async() (or 'fetch_files_async()' if you don't
want something which sound like a cheap getter). It's going to call a
callback when the fetching in done, from where you can do what you are
doing in ovirt_foreign_menu_notify_files, and from where you'll also be
able to deal with errors.
