[virt-tools-list] [PATCH virt-viewer] !fixup Show failed file transfers

[Jonathon Jongsma]

---

Here's a possible solution. I don't think that a "continue" if the filename is
NULL would work well since then you might have an error message with non files
listed. So here I just display the task ID. Not sure whether that makes sense
or not. I could instead use something like "(unnamed file)". Or we could just
ignore the scenario and let gcc print "(null)" for this unexpected case.
