--- Comment #10 from Ken Arromdee <arromdee at gmx.com> ---
I found the cause of this, sort of.  growisofs reserves 256M spare area for
defect management (see http://fy.chalmers.se/~appro/linux/DVD+RW/Blu-ray/ ). 
You can avoid this by adding the parameter -use-the-force-luke=spare:none.

If I add this parameter, the size doesn't suddenly decrease by 256M, and
everything works.

So the problem is a mismatch between k3b calling growisofs using default
behavior that creates 256M spare, but calculating the available size in a way
that doesn't take the 256M spare into account.

That page doesn't mention BD-R XL, but I would be unsurprised if juef17 had
this same problem for his BD-R XL.
