Hi,
Sorry for breaking the mail thread. I have no message id of

This is probably the known CLOSE TRACK/SESSION bug at the end of
a growisofs BD-R burn which started on a blank BD-R medium.
It was diagnosed by Andy Polykov five years ago
http://lists.debian.org/cdwrite/2008/07/msg00092.html
"Trouble is that when growisofs pre-formats the blank,
it fails to instruct finalization procedure about it.
[...]
You might want to consider explicitly pre-formatting media with
dvd+rw-format [...]
"
From comparing the code which inspects the submitted medium
and the code that formats a blank BD-R, i came to this patch:

The patch was tested with success by Frank Griffin

Fedora has adopted it for testing and it seems to help

Reasoning of mine why the patch should help (or at least not harm):
