Hello Moritz,
You hit the problem: the copy of ffmpeg I was using was quite old - did
just recompile the latest version from git, plus did update the box
where it runs to the latest stable debian version (8.3), and it runs
like charm now! Video plays fine on raspberry pi, and can be started
from any segment, what was my goal.
Thanks, again,
George.

If I'm not totally mistaken, this version of ffmpeg is from around
October 2014. Could you also please test a newer version?
So, how it can be that key frames are invisible in the output produced
by libnvenc? And if so, how the stream can be played normally if there
are no key frames in it?
Some sources on StackOverflow, which may or may not be correct, claim
that Apple HLS indeed requires keyframes in each new segment.

http://stackoverflow.com/a/11644887 (answer to the question above).
I have no idea though, nor how to get ffmpeg and/or nvenc to ensure
this.
Moritz
