The image copying code was refactored in an earlier patch to be

This is not quite accurate. It doesn't explain the seg. fault. This
didn't happen in my patch and I am currently using my own version of
nvenc.c where it's working fine and without the re-factoring. I will not
make a second patch, but see Timo being in charge of this as he is the
one who signed it off. I am going to "do the Pope" and have a little faith.

Can you send a full backtrace of your segfault?
I've updated my git clone and I did a fully compilition just to be sure, but it
still occurs. Funny things is it's working when run from within gdb, but core
dumps when run from the shell.
