It does this whenever I add a folder then attempt to do a contents picture scan. It seems to be a 100% failure rate for me right now, but it did work somewhat recently so it's possible the most recent Sierra update broke something.

Similar problem - worked once, but not again after pruning some subfolders and re-arranging others

I haven't spent a lot of time on this, but it isn't trivial to reproduce. A workaround would be easy to implement, but it would be better to find reliable steps to reproduce first.

Same problem here. Worked the first time but now it won't work. Tried reinstalling, no go.

These errors are probably all duplicates of #439, which should normally be fixed in v4.0.4.
