I guess I marked the wrong package, as Ubuntu doesn't provide any easy mechanism for the end user to figure out which fucking package a given application belongs to, so one has to guess.
I am using standard Ubuntu 16.04, not Lubuntu, and this is about the default screenshot grabber that appears as "Screenshot" and that is launched by pressing the PrintScreen key.
I think the executable is /usr/bin/gnome-screenshot
