I'm marking this bug fixed and close it because it does not affect
any package in unstable/testing.

I believe there was an unintended ABI breakage in FFmpeg and
it caused the kodi crash but since no one is really interested in
debugging that after recompiling solved it there is little value in
keeping it open.

In #797965 Christoph provided a way of reproducing it:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=797965#126

Andreas even provided a patch thus I believe it is a valid bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=797965#116

If I ever find time I'll create a reproducer based on Christoph's
guide, but it is unlikely to happen before Stretch's release.

Closed that one, thanks.

Those are known limitations of the Debian package and the bugs'
state reflects that.

Marked accordingly, thanks.
It can be closed with uploading a new upstream release containing the fix.
I don't think that this issue warrants a back-port.

Cheers,
