Pressing CTRL+C in uvt-simplestreams-libvirt sync removes all files in directory

[Jeffrey Bouter]

If CTRL+C is pressed whilst uvt-simplestreams-libvirt sync is syncing an image, all files in used directory are removed. (default: /var/lib/uvtool/libvirt/images).

In my specific case, /var/lib/uvtool/libvirt/images is symlinked to /vms/uvtool

Host OS: Ubuntu 14.04 AMD64

Hi,
I'm checking bug that are idle since some time.

For this in particular I think it actually works - or - we need better info to reproduce.

Above shows it was syncing trusty, and I aborted via CTRL+C, but still the artful image is still around.

@Jeffrey is there another ingredient for you to force this?

Maybe only on Trusty
