All you did wrong was to use buggy software.

As other people have mentioned, you can't copy and crop at the same time, but
if the software were properly written this wouldn't cause a segfault either.

It seems to be a common belief by users (and unfortunately relied upon by far
too many programmers) that if a program crashes horribly the user must have
made some mistake, but the truth is that if a program crashes horribly (as
opposed to, for example, printing an error message which actually identifies
the problem and exiting) it's ALWAYS the programmer's fault.
