Comment 15 for bug 853373

Confirm, still happens, seems a bug in libgphoto2. Seems dangerous, if you trust shotwell for the photo download and after that you format your card you can loose (a lot) of data.

Moreover, if you after the fact import the photos from a folder, it seems to download the RW2 files, but they are nowhere to be seen.

Why it is "Invalid"? It can lead to data loss. It's a critical one, and makes shotwell not useful at all.
