the errorlog only shows the camera no longer accepting commands :/

The tail end of logfile of the call before that would be interesting, (can start after the big images has been downloaded)

It always appears when using reuterbal/photobooth with preview enabled. Which is using the python-gphoto2 I couldn't reproduce it with gphoto2 on the cli yet, but perhaps it can be helpful for debugging.
